Projection goes through mesh and hits the inside creating two images


#1

I don’t know whether this is a renderman or maya issue but I’ll start here. So I’m trying to project an image into my mesh, but I only want it to show on the first wall it hits, not the one on the inside. I’m using renderman nodes only with the exception of the “Place3DTexture” node that works with renderman.

I followed this tutorial https://www.youtube.com/watch?v=IHqQz3KCdpk and he doesnt rotate around the building so I can’t really see if he gets the same issue or not.

  • have set the ST Wrap mode to Black and Black within the TX editor.
  • My image has a correct alpha

Below are som images of what I got going on. Just tell me if you need any more information.

For a fast fix i would clone the shader without the projection and assign it to the inner part of the mesh.
