Copy vs switch blending modes?
Does anyone know the difference? I couldn't figure out it sincevthe first version of substance designer? Help says something cryptic: In copy mode it's just the background "covering" the foreground In switch mode, we melt together the both inputs, deciding which one is more influent.

That said I don't understand this alpha choice either . See no difference in 32 bit mode I usually do my substances due to more predictable and unrestricted height… -

premultiplied is useful if you have black in the transparent pixels - not something you see that often these days cos we have image formats that aren't shit I'd imagine people use copy because they don't know what switch does :D also I'd say 1ms is well within margin of error
