A way to compensate UV distortion?

[kirkr5689]

I am trying to do a procedural model  where  the mesh deforms  a bit  when necessary .   Without  re-doing textures.    Like in this example.  Certain  texture space  squeezing to the right is expected  because I want the center point keep  it's coordinate in texture.    But how can I  make top and bottom triangles  keep it straight?   

I appreciate any  idea how can it be compensated for alredy built texture ?   I can pre-bake each triangle having its own vertex color . It's sort of automatic in Blender    and use colorID  it as a mask  plus distorted UV  exr  as distortion vector   but what's next?

Keeping the centre UV co-ordinate, not changing the texture, and having the texture align differently appear to be contradictory requirements.

You could reproject the texture in Blender , in UV editing hit 7 to view from above (orthographic) then use UV Project from View. That would keep the horizontal and vertical lines aligned on each side.

Thanks Dave, you are probably right it's impossible task.
