Hopefully this is a softball for all those material/texture guru’s out there…
When you use the texture sample node, does the sampler only interrogate those samples which are covered by the UV map of the assigned mesh? Meaning, if I had a single 8k texture and a bunch of small props using it in a material, am I paying the cost of the sampling the entire 8k texture for each prop or is the texture sampler only going to evaluate those samples covered by the UV?
My gut says only those covered by the UV but I just want to be sure. Thanks!
