    Ha, subdivide worked damn, never tried it before... thats huge for us tbh, thanks for the tip. The geometry is not welded, and breaks if I try to weld it, and I'm unfortunately not allowed to send you the mesh. But since subdivide worked I guess I can continue testing fur, finally I'll keep you updated.

    Edit:
    Subdivide worked for most geometry, not all when the curvature become more complex, subdivide will cause meshsmoothing to fail.

    @samuel_bubat
    Yeah I know, but this simple geometry is just a small part of what needs to be remodelled, and we don't have time. Actually I barely have time to write on the forum..
    Turn to poly didn't work, it broke the mesh

      ahh youre trying to meshsmooth the imported geometry too? sounds like a nightmare

        Nah, I meant smoothing groups smoothing. What should you call that? Isn't it meshsmoothing as well? Anyway, not the meshsmooth modifier

          and nothing a careful use of the "smooth" modifier wont fix?

            No I actually have a headache now.. Hopefully I get some time over soon for testing fur and displacement again with the subdivided geometry. So difficult to get time for testing...

                maybe im a bit late, and i havent read the whole tread, but cant you set the vHair distribution settings to per area and not to per face and that would solve your distribution issue??

                  haha.. yes it helps to read the whole thread. the whole point was using per-area wasnt getting the expected results.. and how subdividing the mesh can help, but was causing problems witht he cad geometry he imported.

                    Finally had a couple of minutes to test the subdivided geometry, and it doesn't work the way I want it to.. look at the screendump. The piping around the carpet gets alot more hairs because the geometry is more dense.. but should'nt "per area" fix this problem?

                      with per area you should have even amount all over.. are you talking about the final render or the viewport preview? cos the viewport preview does tend to exhibit that "per face" effect, even if the render is fine. (see attachment, i made a quick model with similar properties, one big face in the middle, lots of little round the edge) subdividing the mesh should simply help a lot with ram usage and speed up yer renders like 10x

                        No it's both in rendering and viewport. You got the result I expected from my own testing.. I wonder why it ain't working for me..

                        I need to keep on testing, thanks for taking time and help out super gnu!

                          Phu, seems like "per area" workes after all, It just fooled me a bit. When applying a small amount of hair the larger polys seems to have alot less hairs, but when increasing the number of hairs per area, the larger polys will reciever more hair than the small ones. I guess it some kind of exponential amount curve or something..

                          Anyway, it works now, after increasing the amount of hair per area and subdivided the mesh a fair bit. And it looks great thanks all

                            For future readers, just remodel your base mesh, you will save a lot of headaches doing VRayFur. Promise.

                                How so? Why couldn't you remodel something almost perfectly with a cad model reference?
