Rendering errors with RenderMan
 

Hi everyone!

I’m posting this request for help, after some time spent trying to fix a problem I’m having with the training course “Introduction to RenderMan for Maya” from Digital Tutors.

The issue is quite peculiar and I’m quite sure that there is indeed a problem with the sample scenes provided with the course. However, I still do not understand why some particular errors only happen when utilizing the RenderMan renderer.
I’ve noticed that all the tutorial scenes are using file paths for textures that refer to a Z:\ drive, which of course does not exist on my workstation. As a result, despite the fact that I’ve correctly set all the file locations in the project property window, I still need to browse my HD for the right texture files so that Maya can render the scene properly.

Anyway, it appears like RenderMan is still searching for some files with no success, since I’m still getting errors in the command feedback area (Cannot find Z:\… etc…)

I was wandering if there is a quick and efficient method to check the file references in a Maya scene. At the moment, I’m away from my workstation and cannot be more precise with respect to the error messages returned when rendering with RenderMan.
Anyway, I noticed that the files reported as missing have the extension ‘ip.txt” (or something like that) after the typical extension .jpg /.tif

Hope to receive some feedbck on this from the experts of the forum.

Thanks a lot,
Mark

If you post up your error messages I will see if I can help you.

The files are probably .tex files which is renderman's default texture format. So what you're saying is it can't find the files? you can use Slim to check the files, there is a box you can use in the shader window to show you the texture file and if it doesn't exist it will tell you. You could always use slim scripting to go through all the texture file attributes on the shaders and tell you which ones don't exist.

Thanks for your reply!
I'm attaching to this post two text files with excerpts taken from the Output Window and Script Editor, so that you can check the error messages.

Could you please also indicate where I can get more infos on this Slim scripting you mentioned, or about that box in the shader window? Anyway, I will give it a look as soon as I can put my hands on Maya this evening...

For the moment thanks a lot for your time. It's really appreciated.

Cheers,
Mark
