Hi
In a RenderMan Ris Rop, i want to output an AOV matte for all objects
using a Pxr Disney shader. I'm connecting a Pxr Matte ID node
where Matte Texture 0 is set to 1,0,0 into the “inputAOV” port of the
Disney shader. So far so good.

In the Ris Rop i have one AOV. What is the correct parameter name for the
“ri_aovariable1” field in the Properties -> Ri AOV tab in order to generate
the output from the shader into the red channel of this AOV?

First I thought it was “matteTexture0” since that is a parameter on the Pxr
MatteID node, but it doesn't seem to work. I also tried “MatteID0” and “color MatteID0” as this is mentioned in the Renderman docs: https://renderman.pixar.com/resources/current/RenderMan/PxrMatteID.html [renderman.pixar.com]

Any help appreciated

I'm pretty sure the correct name is “color MatteID0” but i must be doing something wrong because I can't get this to work.
Any ideas are welcome

Hi bonsak. Did you ever find out what was wrong with this? I'm trying to do the exact same thing (with RenderMan 22, though) and I don't get the matte I want.

I know i figured it out but i cant remember what the correct solution was Sorry
