[Sidefx-houdini-list] OpenGL ROP with transparency?

Yes- I started with UVQuickshade (and no material) and it didn't work properly in the OpenGL ROP- though it works fine in the GL Viewer.
The help doc for the OpenGL ROP said the Medium and High transparency settings only work with an assigned shader so that is why I tried the shaders.

It might be something specific with the shader, as UVQuickshade with
some transparent textures, object level materials and a test of multiple
materials via Material SOPs works for me.
Incidentally, the GL renderer setting only works in hython/hbatch.
Otherwise it uses the same renderer setting as Houdini is currently running.
If you'd like to submit a bug with the hip file that would help in
tracking the problem down.

This was fixed in June in 12.5.437, and in H13 too.
