> Quote - **MikeJ**: I may have misunderstood. Are you seeing that distortion on the low-res mesh already, or only after subdividing once?

Well, I'm not sure what's happening, or what I'm looking at. ;-)

Here's a screenshot of 3 copies of the same head. This is the one I uploaded the other day, with the new UVs based on the "Antonia-template-lo.obj" file you uploaded to the dev site.
All of them have the same UV checker applied.
When I say "distortion" in this case I mean the distortion along the edges of the little black boxes of the UV checker, not the size distortion of the boxes - the little squiggles.

The head on the left is straight lo poly, nothing done to it. The one in the middle is when I put it into subdivision surface (aka sub-patch) mode in LW, and the one on the right is is after freezing it down to a high res poly version of the subpatch version.

The middle version and the one on the right actually have less distortion than the one on the left, the lo poly, no subpatch version.
.................

So as I said, I mapped this in UVLayout using the SUBD mode, as opposed to polygon mode. UVL doesn't actually subdivide it in the preview, but I guess it internally adjusts the UVs for when the model is placed in sub-d in another program. Which is fairly evident in the fact there is more noticeable distortion in the polygon version, than in the sub-d version or the high-res, frozen-down version. And which is what one would expect.

I honestly don't know how to compensate for this. Clearly I can make a decent high res version by either mapping the low res in SUBD and subdividing it, or outright mapping the hi res itself, as I've already done.
But to do one that works the same on both the lo res and high res... like I said, I have no idea how to do it perfectly.

So, how did YOU do it originally? I know you mapped the high res version first, but how did you transfer that to the lo res version?

BTW, consider this whole thing a test. That is, the one I uploaded the other day, maybe an intermediate on the way towards figuring out the best way to get both hi and lo versions perfectly compatible.
There are things I see now that I want to do over, such as the size distortion on the ears is too much and needs to be fixed to be more even. And I'm not entirely happy with the how the feet turned out either, and want to try something different there.
