Rendering program?

[Ministry]

well,, from ur question i understand that u r very new to the cg world..welcome...
the renderers like mental ray, v ray, renderman r just for renders.. u can't model using them.. what it does is..it using the default render to render the image but it enhances the image quality in different ways with different parameters.
for example.. for calculation of bouncing lights and when u want the most logical output with lights and textures..
enjoy

Technically you can model with Mental Ray. Mental Ray takes up a scene written in a specific format, which, among the other things, defines the geometry to be rendered. Theoretically you could write a Mental Ray file through a text editor, and define shapes vertex by vertex. In practice, that's a huge undertaking, which is why we use programs like Maya to model, and let them create the intermediate file for Mental Ray.

So that's the answer to your question about the interaction between programs, you create a scene in your modelling software of choice, which creates a file written specifically for the render engine describing what to render and how to render it, and the render engine executes that file.

I hope I made some sense... ;)
