Given a texture object (Tex) and some coordinates (UV) this line of code will regularly sample a texture:
return Tex.Sample(TexSampler,UV);
Other sampling types like 'SampleGrad', 'SampleBias' or 'SampleLevel' should work just as fine.

Hi, thank you very much for sharing this, I've been looking for this information, and this seems to be the only place that mentions it. A remark and a question though.
ReplyDeleteRemark: I'm using 4.9.2 now, and it seems that TexSampler should be texSampler (lowercase t).
Question: where did you find this information? I'm wondering what else if possible in custom nodes, but I can't seem to find a good overview. Thanks!
