Thanks, Frank. The light bulb finally came on about the whole paint UVs deal. I understood it in concept for some time now, but couldn't not figure it out in practice.
The first image was my original effort without UV painting. The second and third were UV painted. The last is simply more of a quick scene render and my flower is only 2200 polys.
Pinning still eludes me in practice, but I'll get there. I also need to study this one.

Hi Robert.
Don´t know how you built that flower - but if you´re just going for some bending on polygons I would recommend to make the UV layout and painting in first place (no pinning needed). Image A.
After further modeling the unwrap will look differently
Image B.
Sometimes it could have advantages to work in that order.
So all you might wanna know is that the more the quads lost their "squareness& coplanarity" the more pins you may need afterwards - because the LSCM algorithm
tries to recover the angles between the faces. (hope I got that right )
Cheers

is this happening always or only if you change the 3D model AFTER unvrapping it? I didn't investigate the theory behind LCSM and i have not done so many tests but sometimes LCSM unvrapping generate strange geometries... even for simple objects and seams, as Podperson said in the "wrong UV" thread.
thank you,

Frank,
Thanks. I believe I understand. Paint it in the early stages, when appropriate, such that you know where all the details need to go, but otherwise expect to have a bit of UV layout work to do in addition.
