Setelah beberapa waktu yang lalu tak posting artikel Tutorial Pembuatan Rumah Dengan Sketch Up dan 3Ds Max Vray Bag. 1 saiki tak posting yang bagian ke 2 nya, monggo langsung tancap…
I finally found the time to finish part 2 of Making of ‘MS House’ at dusk, Part 1. This time I’ll cover topics starting from the export of the SketchUP 3d model and up to the final render & post-production. Autodesk released the SketchUP Importer for 3D Studio Max 2010 which allows for a new and probably better importing of the SketchUP model then the 3DS format use described in this article. Next time I’ll keep post parts a week apart at most.
More than a ‘HOW-TO’ but not really qualifying as a fully-fledged tutorial, a ‘MAKING-OF’ post is a collection of spotlights illuminating several different aspects involving in the creation of the subject scene. Hopefully, the information I’m sharing here will be useful for all of you 3d visualization artists, architects, designers and anyone else with an interest in 3d architectural visualization.
My preferred method of exporting the SketchUP model to 3D Studio Max is using the 3DS file format. In the 3DS Export Options Geometry tab you can choose the method of transport :
* Full hierarchy
* By layer
* By material
* Single object
Normally when first exporting the model I would use the by material option. This way I don’t get Multi/Sub-Object materials in 3dsmax and have better control in choosing and editing materials. You can still pick each element in the model regardless, the by material export method doesn’t fuse / weld all the same material geometry together.
For subsequent model updates I would check the Export only current selection after I make sure only the parts I need to re-export are selected. For this I would sometimes use the Single object option, just to make things simpler if the new addition only uses one material for example.
On the first export I also check Generate cameras from pages and I don’t mess with the material options really. Since I tend to model all things as they are in real life I wouldn’t get 2-sided material faces and wouldn’t have any edges to export too (sometimes it is real easy and fast to represent rails with just edges, but before export I add thickness to them).
I also do not use the Export texture maps option, I handle this part in 3D Studio Max, though the assignment and positioning of textures in SketchUP does transfer even without checking this option (after you apply the texture in max you will see the mapping is the same as it was in SketchUP if you use the same proportion image).
I’ve created a new 3dsmax file and imported the 3DS file exported from SketchUP into it using the default settings. After that I usually run the VRay Scene Converter from the quad menu just to start with all materials set to V-Ray. I also take the time to pick materials and assign related geometry to layers such as window glass, pool water, house walls, etc. I don’t change the material names yet, since i know I’ll probably re-export some parts and would like them to keep the same material by using the use scene material option when merging them in. All future imports to the work file will start by importing the 3ds file into a clean new 3dsmax file first and then merged into the work file. I find this method is keeping me out of many troubles.
Initial ambient occlusion render
I’ve integrated this render method, as described in the post about Using VRayLightMtl + VRayDirt for Quick AO Render Checkup, into my work-flow after reading a tutorial by Gus Capote form Preconstruct in the 101 issue of 3D World Magazine. I love to use this method while I explore the scene for camera placements and blocking out additional geometry. This way i keep my focus and don’t bother myself with lighting and materials other then turning glass elements on / off to see how the scene look with and without it.
I use LWF for almost all my work. You can find a great explanation about this in the following links :
I’ll just show how I set it up hare and mention that I burn the 2.2 gamma into the image. While this is not considered the proper LWF method it works fine for most of what I do.
For lighting this scene I use an image created by Valentijn Kint, you can find his great sky images here. I place this texture in the environment slot of the 3dsmax Environment and Effects options dialog
I use the image as is, and just offset it so that the bright area will show on the right side of the image. behind the tree line. I enable view of the background image in the viewport so that it will be easy to set it up the best way. As a general rule i strive to achieve a wide range of colors and brightness levels in the background adding to the image impact. This kind of backlit situation plays rather well with interior lights and i prefer this over pure night shots.
V-Ray physical camera settings
I’m using a VRayPhysical camera to render this scene, with settings as listed below. I try to use real camera values since I can relate to that (The ones you can actually dial in on a camera). I normally start with pure white for the white balance and change as i need along the way – for this image i didn’t, all the tone mapping was done in post later.
* Focal Length = 20mm
* Shutter Speed = 1/60
* F-Number = 2.8
* Film Speed (ISO) = 200
* White Balance = 255, 255, 255
* Vertical Shift Correction = On
* Vignetting = Off
Before choosing the final settings for the background image and camera I rendered a set of 10 images, with an override material applied, offsetting the background by 0.1 each time. Today it’s possible to do with V-Ray RT without any test renders, just change it and see it on the fly!
After setting the desired background offset I test the scene using slightly better render settings with and without the window glass and pool water, and also test it with them but apply a 100% reflecting materials to those elements to get a feel of how the maximum reflection looks. I f i need to tweak the background a little to show better reflection too this is the stage i do it in. After that I quickly tested the scene with glass and water elements turned on and excluded from the general scene material override..
I’ll focus now on some of the more dominant materials in the scene, elaborating a little about the textures and settings i used for the windows glass, pool water, pool tiles, wood deck, wall plaster and grass
For the glass I’ve set the diffuse slot to pure black. Reflection assigned a falloff map set to Perpendicular / Parallel and edited the mix curve so that its not pure black and white at the edges, this way it will never fully reflect or refract. Retraction set to pure white with IOR set to 1.545 and a standard noise map for bump set to 1% to imitate real life glass distortion.
Pool water material
The water material is tricky since it’s really a combination of the pool surface and water that creates the final effect. As the glass the diffuse here is also pure black. Reflection set to RGB 185,185,185 with Fresnel turned on, IOR set to 1.333. Refraction set to RGB 240,240,240 with Fog color of RGB 60,240,225 and a multiplier of 0.02. A a standard noise map assigned to the bump slot at 8% to recreate the water surface.
The pool tile is a combination of maps i got from one of the evermotion packs. It uses 3 images for the diffuse, bump and reflection map slots.
Wood decking material
For the wood deck I’ve used Arroway’s boards+01 texture form their general texture pack.
I picked up this grass material from evermotion forum after a kind user shared it, I can’t remember who it was though (if you do, please mention this in a comment below). It is a mix of 3 grass diffuse texture and a grayscale texture for the V-Ray displacement
Bamboo like plant
I used the advanced painter script to paint grassStrands and assign this material on them to look more like a bamboo type plant. The effect is great from mid to far camera placement. Near shots may not look that great with this setup.
Inside the house i placed several VRayLights near the ceilings with a little bit of orange in the color slot. For the pool i decided to go with standard spot lights so i can have more control over the direction and spread of light inside and outside of the pool. Here are the settings for both the VRayLights and Spot Lights.
The vegetation in this scene is a combination of Onyx, XFrog and Evermotion models placed either manually or scattered using VRayScatter. The background trees are made out of two VRayScatter objects, each with a different tree (An onyx custom broad leaf and XFrog conifer). Both materials were tweaked to use the VRayScatterMap to allow for leaf color variations between tree instances.
The small areas of shrubs were define by drawing a line shape that was then converted to poly to become the distribution geometry for the VRayScatter object (the poly object was set to not render).
Render settings are rather simple and actually weren’t optimized that much. You can see them all in the image below.
The initial render was not a good sight, but i was planning on doing most of the tuning in post. I’ve done some general color and level corrections and also specific tweaks to the pool area, window glow and trees in the background until i was feeling good about the atmosphere. below you can see the initial image, mid process image and final result.
Pemodelan objek diatas berawal dari sebuah denah yang dibuat di program Autocad, kemudian dimasukan di program sketchup, lalu di program sketchup itulah dibuat pemodelan 3 dimensinya, kemudian untuk hasil akhirnya objek tersebut kita export ke program 3 ds max (cara mengexport lihat artikel sebelumnya, makanya langganan argajogja ben ra ketinggalan, he3x) lalu kemudian di render menggunakan plugin vray. Gambar diatas adalah gambar hasil akhir dari renderan menggunakan 3 ds max vray.

More than a ‘HOW-TO’ but not really qualifying as a fully-fledged tutorial, a ‘MAKING-OF’ post is a collection of spotlights illuminating several different aspects involving in the creation of the subject scene. Hopefully, the information I’m sharing here will be useful for all of you 3d visualization artists, architects, designers and anyone else with an interest in 3d architectural visualization
The first things I usually get from a client are the CAD drawings for the project at hand (a rare few manage to send me the down payment first). These files will be the baseline for the 3d model to be created and it is very important to set them right to prevent problems down the road. as you can see below, the original drawings sent by the architect contains a large amount of information we don’t need to transfer to SketchUP
what you see on screen initially is not necessarily all the content inside the files, some parts might be far away from each other. Zooming extents will let you know if this is the case with your file and you can act accordingly by moving or deleting parts of it.
Check it sideways
I know this sound odd, CAD drawings supposed to be 2d no? but believe me, sometimes they come more 3d then your 3d model will ever be. most times only site survey contour lines will spread along the Z axis and some additional information related to that and its OK, the problem is some draftsman snap to those lines while viewing the plan in 2d top view never knowing they go up and down the Z line. you really don’t wont to export that to SketchUP.
The best solution is to use the Flatten command and when it fails (and it will) try to change the Z and Elevation values for the drawing object from the properties panel. it’s tedious but well worth the effort. SketchUP has a ruby script that can do that too, but i wouldn’t try it on complex drawings though.
Check the drawings for xref’s and bind them in if you need them, SketchUP will ignore them on import unless you do. sometimes Blocks behave the same and you can solve this by exploding them before export.
Do not delete information you don’t need, just hide it while you manipulate the file. I usually hide all the dimension lines, text, hatches, vegetation and basically strive to end up with just the bare bones of the design. Sometimes I’ll keep furniture layers or Hidden-line layers and rename them to something descriptive for later use in SketchUP (i can just hide it back there too).
Purge, Audit and Copy Paste it out
After all is hidden and the files is rather clean, I’ll run Purge and Audit to make sure all unnecessary information is out and errors are fixed. The next step will be to select all and copy it to be pasted into a new file at the origin location (0,0,0) – this is very importnat. The original drawings might not be located at the origin, but rather far away from it – SketchUP doesn’t take it too well if things are far away from (0,0,0). Pasting it all in a new file takes care of all that, and also make sure you only get what you need in the file.
After doing all that is mentioned above, you can safely import the CAD file from within SketchUP, just make sure to take note of the units used in the drawings and set the same units in the import properties panel. choosing ‘Preserve drawing origin’ will keep the imported drawing at it same location relative to (0,0,0) as in the CAD file – if not, it will be move to the SketchUP origin automatically, which is good if you forgot about copy pasting it manually like i mentioned above.
Organize your layers
After the import I’ll make sure it all looks OK and delete almost all the original CAD layers to prevent clatter in the list. I usually keep the furniture, hidden line-work and vegetation layers for later use (and hide them most of the time).
Check the lines
Using color by axis view mode will allow you to examine the line-work and spot potential problem areas. sometimes lines just look parallel to each and only when you are deep into the modeling stage you discover issues related to that. Spend some time checking the lines with this option just to make sure all is well.
Group it all up
It is good practice to group all the content within a SketchUP model, since layering is only a visual separation in SketchUP and hidden data can merge with new data if you are not fully in control of what you do. I would make groups of each plan, elevation and section and position them in 3d, essentially building a rig or scaffolding from them.
Since the modeling of the house is not in the scope of this post I’ll just show some parts and share some tips related to it. Just add a comment below if you would like me to share some more information specifically about the modeling.
Adding some high detail
True sharp edges are hard to come by in the real world, almost everything has some kind of a bevel to it at the edges and this is the part that picks up the light showing a nice highlight. here you can see a part of the stone cladding on the facade were i modeled the beveled edges using the SketchyBevel v0.1 script by Chris Phillips. Another script you can use to round edges is RoundCorner 2.1a by Fredo6.
You can also see, in the image above and below, the modeled shading louvers i created for the windows along with the wires that suppose to lead them on the way up and down. This might be considered as overhead for some but as i really like it if i can render some closeup shots and then this really looks good (though for extreme closeup’s it’s still lacking)
You can some more layers of detail by adding curtains behind the windows. Here is a quick video showing how a simple curtain can be modeled in SketchUP using the freehand tool, FFD (Free Form Modifier) script by Chris Phillips and also the Subdivide & Smooth script by Dale Martens. I’m also testing screenr.com recording this video so bare with me please.
If you are not sure, group it!
Don’t just leave things hanging out there in the model file, keep it all in groups & components. Like i mentioned previously, SketchUP layering system is visual only and must be backed up by arranging the geometry into groups (that is, if you want to keep control over any kind of model). I make it a habit to keep all lower level geometry in default layer 0 and only send groups & components to other layers.
Don’t be afraid to create many groups, you can explode and rearrange them later, separating geometry later is more difficult. I know that all the lines showing in the model could be a problem if you intend to produce purely SketchUP images, but if it is to be sent for rendering with V-Ray then that’s not a problem at all.
Facing the right direction
Initial SketchUP model show only 2 colors representing the front and back side of the faces (the Normal side and the opposite), But once you start adding materials and textures that visual Que is lost and things can flip on you. Use the monochrome view mode to catch potential problems and correct using the orient faces command before you find it in 3d Studio Max.
Try to add as much material and textural information in SketchUP as you can, this will save a lot of time later on. For a project that goes to 3d Studio Max i wouldn’t even care about the colors i pick and if they represent the actual material in the real world, for me it’s just material separation since i export the model according to it. For simple planer mapped objects i would take the time to apply and map the diffuse (color) image so to get it right in 3dsmax later on.
In this post I described some aspects of my SketchUP work from getting the original CAD drawings and up to the finished model. I hope you find this information helpful and please feel free to comment below and use the share this button below to let others know about it too.
In part 2 i will cover topics starting from the export of the SketchUP 3d model and up to the final render & post-production (I hope i can get it all in just one more part).
