Hi! Great and informative as always and easy to follow. Im very interested into answers for the following: So we kinda paint the texture and support it with contact shadows "and bumps" by baking these specific maps, right? And we can even use our self painted textures to influence the geometry in the node editor by using color ramps which influence the factors of the shaders.
Since we painted them directly on our laid out UV maps, what about external textures from sites such as polygon? They aren't painted onto our UVs so how can i "cut them down" to our UVs without stretching them all over into our zero to one space?
Just curious while im learning! Thx for ur time!
Unfortunately I'm not a member of Poliigon and I can't say 100% how the textures are presented there. But they're likely just high resolution photos taken specifically to be textures. At best, they've been modified to be tileable.
Either way, they can certainly be used with a model's UV's. The same way we projection-painted (stenciled) the pancake texture in this course, you can also do with poliigon or other photo texture source.
