I was digging through the rv reference docs and noticed there is support for texture samplers, however no real usage example exists that I've been able to find. I'm struggling to come up with how I'm supposed to bind a texture and then sample it. The docs make it seem like I just define a huge array in the parameters section of the gto file but that seems odd.
I'm trying to load a .cube file and sample it in glsl to apply and addition color LUT on top of whatever is already in the node stack. There are other ways to do this for sure, but in this case doing it after all of our OCIO stuff is resolved is ideal.
Can someone show a trivial example case of using sampler3D as a glsl input?
