I've some difficulties to find a satisfactory unwrap solution for this kind of long angled object with uneven segments:
I'm only interested in the brown faces which are delimited by two seams.
The solution must preserve the relative length of each straight segment, so that the texture containing a repeated pattern can be mapped evenly on the whole length (the sample is a ceramic baseboard).
Here is the result with a cube projection and a checker texture, other methods provide different results, but the distortion is always present:
I can't find a solution, except purely manual, to create the UV map while ensuring all segments:
- Are oriented in the same direction on the map,
- Have their length proportional to their actual size, to prevent texture distortion.
These constraints seem quite common, is there a standard approach?
Intuitively, I'm expecting the most simple method to lead to overlapping variable length rectangles, in the same direction, anchored at a corner (or a very large single rectangle).
