Here is an example. mtlxgeompropvalueuniform will read file primvars. You don't want to use strings, as asset path primvars get resolved, and is what you should be using for file paths. Also the primvars need to be constant (i.e. a single-value for the prim). You can't interpolate strings across faces or points. On PointInstancers, those primvars are technically vertex-interpolated, but they still follow the same rule, as each instance gets only 1 value.

The helpcard for mtlxgeompropvalueuniform [www.sidefx.com] was messed up. It will be correct when the online docs are updated tomorrow, after with tomorrow's build.

Hope this helps!

Sorry, we don't have plans to record these workshops.

So I suppose the red dot simply means "you're not using scene light"...?

Yes that's a good way to think of this, for the lighting override buttons. I like to say the red dot, whether in the Viewport buttons or the Scene Graph Tree, means "My appearance in the Viewport is altered by this option, so I will look different when rendered/saved to disk."
