[Closed] mental ray scripts

Not exactly, but close.

The MAXScript exposure of mental ray features (especially shaders) happens more or less automatically. Discreet developed a system which parses the mental ray files and defines classes and corresponding UIs with spinners, checkboxes etc. for all controls in the files on the fly! The mental ray Materials you see in the Max Material Editor have not been developed by humans, they have been generated from the shaders’ definitions and thus are more dependent on what the shader developers did (mostly mental images guys) than on what the Discreet developers have done while parsing them. You will notice some obvious problems with parameter names containing invalid (in MAXScript) characters like spaces. While you can access them using single quotes, and the parsed UIs also work as expected, nobody can guarantee that all the automatic MAXScript exposures will work 100%, and nobody can expect mental images to change their shaders’ code just because MAXScript does not like all of them

So even if all these features had been tested, some would have remained known problems and limitations. What must have been tested is the mental ray shader parser (you probably remember that the original mental ray connection for R3 did not support 3rd party mr shaders, this was new in Max 6). The “Unsupported feature” means that if you happen to find a problem, Discreet most probably cannot fix it anyway because the cause might be in the 3rd party shader code and not in Max itself…
