Other than the glacially slowness of Houdini with a simple layer mix, I'm finding that Houdini 19.501 doesn't seem to accept parm outputs if one collapses material nodes into material builder. In the attached example, the nodes without builders work fine ("MyShader") but when I collapse them ("MyShaderBuilt"), the layer mix renders black. Is this a bug or user error? Thanks.

You were nearly there. The builders were just missing the uv coordinates connection. I've attached an edited scene.
