Getting sss to work with point instance procedural

[mikelyndon]

Hey guys,

I was hoping someone could enlighten me as to why I can't get sss to work with the point instance procedural. I'm using pbr. If I turn all components of the surface shader off except for sss and try single scatter the instance object renders black. If I attempt to render with multi scatter the render seems to get stuck on generating the point cloud.

Thanks

Mike

Do you have an example file we could try ?

Here's a simple setup to look at. The sphere on the left renders with sss fine but the instanced object doesn't display single scatter sss in the render. And if I turn on multi scatter it doesn't even render.

Houdini 12.0.663: Fixed sub-surface scattering to work with point instancing by introducing a new scope, "scope:self", which allows scopable raytracing operations to safely restrict themselves to only the currently shading object.
