Nothing's wrong with maya, i just got to used to it. Maya and Houdini are really different. So i got ambient occlusion working. I slim all i did was create a matte shader with an occlusion node attached to the matte shaders diffuse illumination. I had some problems with rmands though. I created an otl but in houdini the shader throws lots of 31004 not a parameter of shader. I set the parameters to external in slim, but i am not sure what else to do.

Thanks again for you help.

Xcomb,

Genious! I forgot about turning on raytracing through the sop(been using too many different programs lately, stupid maya).

I will give this a whirl a let you know what happens

So i am starting a new animation project with a group of students at the university of texas at dallas. I am currently trying to integrate houdini, maya, renderman, nuke, boujou, vegas all into one beautiful animation. Most everything is going well. but i keep running into weird problems regarding rman shaders and houdini. And it is totally because i am pretty ignorant of th subtlties they provide.

Regardless, i was wondering if someone could clue me into how rman ambient occlusion works in houdini. I understand how to build the suface shader. but i am not sure how to build the light shader and force rman to ray trace.

Any ideas?

thanks in advance tony
