I have a mesh unwrapped which I need to ensure that each face of same size occupy the exactly the same texture space (pixel-perfect).
This holds true when I simply use the basic unwrap option. However, when I select the concerned faces in the UV/Image editor tab and scale them at once, the resulting faces loses proportion.
I think the problem is that I can only scale the faces based on one pivot point, hence the faces are scaled differently depending on their respective distance from the choice of pivot centre.
So, I am wondering if there is any option available so that each face is scaled using their own centre as the pivot point? Otherwise, does anyone know how I can achieve what I want?
