Curious thing I just came across and don’t fully understand. So I am using Lunchboxes Reverse UV component to set some surfaces’ (just rectangles standing upright) UV directions since I am using Panelling tools to create grids on them. So far so good.
Now I have some rectangles that are the other way then I want them (UV 0,0 is top right when viewed from the front rather than bottom left, which is the default), so I built a little something that just checks which directions things go and then reverses accordingly.
What I noticed though, is that Reverse UV does something different to reversing U and then reversing V. Basically UV go in the same direction as before when using that option.
Using Reverse UV from Lunchbox (option 3). note how U and V go in the same direction as before:
Using Reverse U, then Reverse V:
Why is this happening? Is it just a bug?
