Cannot flow object along surface

Hello guys,

I am trying to flow this red model skin along this grey surface, but the patern won’t cover in the right and linear way as it should.

Some one could help? I really cant figure out what I am doing wrong.

  1. UV layout very poor
  2. Is underlying surface
  3. Surface is polysurface, flow work’s only on single surface.
  4. For this surfaces Flow is not the right tool use Paneling Tools, is extended Flow with more controls…

Correct 1 and 2:
Use command Explode,
Rebuild long surfaces -> use command Sweep Two Rails ( under menu surface), here select long edges as rail and short edges as profile. Delete old surfaces
Correct 3 and 4: Use Paneling Tools, each once for each surface
