I have exactly the same problem as it was described there: Texture distorted on UV unwrapped face The texture is distorted (kind of "skewed" or broken) on a trapeze-shaped face.
But the solution provided there does not satisfy me. I need Blender to better interpolate a texture stretched over a single trapeze-shaped face. I can achieve this by subdividing my object, using "simple" method, but I would prefer to avoid that. I want to keep my model low-poly.
