Hey i trying to render a realistic car and I used mentalray materials,Now I need to setup render passes for it and not able to do so. I am using maya 2008 and I used Final Gather by using Image Based Lighting and one directional light. I want the following passes: Diffuse,Reflection,Occlussion,Specular and more if possible. Please Help.

Hello friends, I want to get a good reflection on a thin one sided surface (headlamp). I use the arch and design (Thin Geometry) shader.. but for some reason.. the glass just looks transparent... I don't' want to change the refraction cause the glass should be completly clear. But even if my reflection is totally white (full reflection) it's just transparent.. what do I miss ? thx ...

I'm looking for an explanation as to way Alpha layers don't render out for particles with instanced geometry to them in Mental Ray. Hardware Renders out the alpha, but not MR. Does anyone know exactly why this happens, and is there a way to obtain an alpha for particles in MR? If it weren't for the fact that I've got a random rotation expression that changes how the particles move every ...

hi, im creating a character, and im having a huge trouble setting up a shader for the eyes. the eye geometry is the basic: an external layer, shaped like a ball with a cornea, and the inner eye, a ball that is the sclera with is front flattened for the iris and a hole for the pupil. turns out that the shader never turns out good, or it reflects too much or it wont reflect neither the lights very...

So,now I used the same Image as HDRI and and got pretty satisfying results but now I want to match the shadows,I am really confused!... I tried using directional light but I am getting very light shadows. Is there anything that we can do...

Hi guys and girls. We are working on a liquid commercial and need to simulate lots of air bubbles floating around...no problem. Mental Ray assumes the camera is in a vacuum, where in our case, we need it to think it's in IOR of 1.34, so that the air bubbles (with IOR of 1.003) renders correct. We don't have any time on the job to do R&D, so I was wondering if someone knows how to get ...

I'm getting the following warnings in my mental ray Messages Window: My understanding is that "RCFG" is Render Core Final Gather. A page on LAMRUG says it's harmless, and most of what I've seen online suggests that it has something to do with bump mapping causing bad calculations on the Final Gather rays. When I see these warnings, should that be an indication that I need to dial ...

hello, just wondering if there is a way to make the normal map more pronounced when rendered in mental ray, other than increasing the contrast. I tried different lighting combinations and setting the filter to lancroz but it doesnt do much improvements. thanks in advance

I might be mistaken (i'm almost sure that I am), but if you use logarithmic exposure control you could match those values with Photoshop adjustment layers

I was looking at the same thing the other day. I wanted to export some geometry in Max with MR architectural shader, to the mia_material in Maya. I thought that because the shader parameters are identical (not entirely sure but I believe so) there must be a way. http://forums.cgsociety.org/showthread.php?f=6&t=8 30684 I didn't have time to look at the tools proposed, or least I ...

There must be some change because of the new render layers and possibly the new smooth render option. WHile we're talking stereo 3D; do you have any idea why some projects render all the left frames and then all the right frames and some others render alternate frames?
