So does Unreal consider multiple UV sets that are present in a single texture as a single texture? How are the pros and cons vs having multiple textures without UV sets instead in the same material? Is this better for memory and performance in general or is the same thing under the hood?
As an example: One 2K texture with 2 UV sets in the same material vs having two separate 2K textures with no UV sets in the same material. Of course this multiplied for all maps roughness normal etc…
Also I haven’t tested Normal maps in multiple UV sets before, should i expect any problems here with having Normal maps arranged like that in Unreal? or should it work right as expected like the other maps?
Last question is unrelated, but I wanted to ask, does anyone know how many Draw calls Paragon characters have per character? Notably how many separate materials do they have on average?
