I'm trying to learn how to write custom viewport shaders in GLSL, but couldn't find any up-to-date example. I read the relevant help pages (OpenGL Shaders [www.sidefx.com] and custom viewport shader [www.sidefx.com]), but still don't know how to implement basic things such as hooking up a diffuse map. Can anyone point me to a vanilla example?
Many thanks!

The default GLSL shader produced with the steps listed in the second link you provided (https://www.sidefx.com/docs/houdini/shade/glsl.html) seems to work for me.
I tweaked the fragment shader to set the diffuse color to green, and the sphere appears green in the viewport. See attached.

Thanks for the helpful replies mestela and rafal!
mestelaFollowing your suggestion I looked at Labs Quick Material. It's indeed helpful, but it's also the only one I found. Are you referring to any other labs materials that I'm not aware of?
Install sidefx labs, there's several example viewport materials in there that hook up to texture slots.
