So, this may be a silly question, but is there any benefit/detriment to using a single texcoord node as an input for a bunch of nodes, vs separate texcoord nodes for separate inputs? My instinct tells me that re-using a single texcoord node for everything would somehow improve memory use or performance, but my reasoning tells me that it might not. Separate texcoord nodes looks cleaner in the material editor, but I don’t want to waste even a single processor cycle or byte of memory if I can help it.
UE4’s material translator is clever enough to optimize out identical nodes, thus if using multiple nodes looks cleaner, nothing should stop you from doing so.
