"easily generate"What does that mean ?
Yeah, but that still doesn't answer the question - because we have no clue what you already can or cannot do.The texture above is *extremely* simple - it's basically a medium grey fill, with some slight variations for each element (probably planks ?) and a very light texture overlay. This takes about 15 seconds to create in Photoshop with just a very basic understanding of the program, which is obviously a requirement before diving into texturing.Therefore there is a very strong disconnect between what you ask (some kind of automatic way to "generate" ... something ?) and the example that you show, which is trivially simple.I'll reformulate. Generating it ... from what , exactly ?Also : if you are currently not comfortable with photoshop or image editors in general, focus on that for a while first.Lastly, a very important thing to consider :User wants to do X.User doesn't know how to do X, but thinks they can fumble their way to a solution if they can just manage to do Y.User doesn't know how to do Y either.User asks for help with Y.Others try to help user with Y, but are confused because Y seems like a strange problem to want to solve.After much interaction and wasted time, it finally becomes clear that the user really wants help with X, and that Y wasn't even a suitable solution for X.This is referred to as "the XY problem" and this is probably what you are running into at the moment. http://xyproblem.info/
Apologies for hijacking the thread but it's a relevant question.Is there a difference between a gradient and a non-gradient roughness map? Since a gradient implies a gradual transition or fade, how does that translate into PBR science?
