currently I'm diving into GLSL-Shaders with Houdini.
I got a very basic shader to run correctly, but actually passing
useful attributes to it via SOP level seems to be unsupported right now?
I can only pass it regular attributes via the parameters-view if I create
it in the SHOP-context. Neither overwriting any of them in the properties-setup
nor anywhere else seems to change the shader instance.
Any idea what I have to do for that?
Documentation is sparse at best
Also I believe it's unsupported right now to use Geometry-Shaders
in GLSL? (so shading sprites is out of the question?)
