Hello, Jeff, I m doing Revit for now, I think I can model better Arch Models in Revit than Max. I m planning to render Rvit models in Max with MR. But I know that Revit produce huge file size (around 5 to 10 MB) & it is the bottleneck while Rendering in Max. Max Crashes frequently, can u tell me how to lower the size of Arch model in Max or Revit, so that Rendering can be done smoothly. Also do u produce scene files of ur Arch Work, if yes Where I can download it. I know u r master in MR.

"as a general rule of thumb: if the interior scene is not covered by more than 50% of direct sunlight, then GI should be incorporated into the FG solution"
however my scene's look ok when using just FG, but they are really blue (which is expected when rendered with default white material override.
but then when i incorporate GI, the scene becomes really 'overbright' and more white than just the FG solution.
how would i control this??
i must admit the GI inclusion does help out when rendering certain objects within the scene, e.g. cloth curtains
so i would like to be able to include it without giving the scene overkill on the lighting
amitjersy: Afraid I don't know much about Revit (never used it). Perhaps using Xref's would help with those files. Short of that, switching to 64-bit surely would help you deal with any large sized files.
daveb867: I don't agree with that statement, but that's just my opinion based on my own workflow. I generally always use GI for architectural interiors. If the sun isn't really contributing to the scene I simply disable it from generating photons. The Dwayne Ellis scene in my gallery is a good example of this. The mrSun is still in the scene (it's behind the camera, out of sight). But I still used GI photons in the scene for the other light sources. The sun was the only light that didn't generate photons. Again, that's just me...other's may prefer a different work flow.
If your scene is overbright, and all the lights are configured properly, sounds like you simply need to adjust your exposure settings.
Just have to say that your last blog update blew me away.
Every single picture was so photorealistics I had to look at each for a good 15 minutes before I closed them.
That clay material looks insane and I can't wait to try it out myself. I'm sensing that scene must have taken quite a bit of time to render so I guess that replacing my normal clay renders with this will increase my WIP-renders quite a bit, but I'll score way high on style points.
About the cornell box test:
- How did you achieve that warm glow coming from the light? Is it the light we're seeing or something in front of it?
About the bathroom scene:
- The porcelain(sp?) material looks insane. Are you using the A&D porcelain material you posted some time ago or is this something else? I would love to have a look at that material, that is if it's something else than the A&D one because I have looked at that ... alot. :P
The clay material won't slow your render too bad as long as you stick to the highlights & FG only mode for reflectivity. If you use actual glossy reflections it will require a high amount of samples to clear the noise from such a glossy material. However, the fast (interpolate) option would speed up the render if you do choose to use realistic glossy reflections.
The cornell box: The warm glow from the light comes from the glare lens shader.
The bathroom scene porcelain is the porcelain ProMaterial preset. ProMaterials are only available in 3ds Max 2009. However, I'm pretty certain the .mat file I've previously posted in my blog here contains an A&D porcelain material and it'll provide a similar result.
