How to create a reflection map while rendering with mental ray


#1

Hi,

I’m trying to create a reflection map, I must use mental ray as the rendering engine.

I’ve attached a env sphere node with texture to the reflected color slider of my blinn shader. The reflection map works, however it’s still raytracing everything else in the scene. This defeats the purpose of using a reflection map to lower render times.

Is it possible to render using mental ray, use a reflection map but not have that material raytrace the rest of the scene?

Hi!

On your blinn shader, expand the ‘Raytrace Options’ area and set the ‘Reflection Limit’ to 0.

:thumbsup:

EDIT: Oh I just noticed that djx answered you in the Maya section too! :scream:

How do you set this up in the mr Arch Design material (I’m using Max btw)? I tried to do this the other day but I didn’t notice much difference and wasn’t sure if I was doing something wrong.

How do I get it to not raytrace.

On the Arch & Design shader you can either tick the ‘Highlights+FG Only’ checkbox, or under the ‘Advanced Rendering Options’ rollout, you can set the Reflections ‘Max Trace Depth’ to 0.

:wink:
