Subdivisions distort & stretch UVs, help

[system]

I cant get my UVS clean without stretching distortion, read alot on the net, watched videos. What i got of the information is that you should do UVS after subdivisions and not before couse subdivide the mesh will stretch distort the UVs.

So ive tried this, exported my subtool mesh with lowest subdivisions, imported it to 3D coat and layout my UVs, had the same subtool selected in zbrush and imported it back, got the UVs and looks fine at lowest subdivions, but when i subdivide it distort/stretches…how do you fix this?

Its hard to tell what your ZB sculpt looks like, but it appears that your UVs are merely following the contours of the sculpt, and it looks OK to me. Is that checkerboard just a temporary visual?
