Hey folks

I reduce an object with poly reduce in Cinema 4d r18 but after that my uv map was killed
IS there a trick to preserve my uv map?

Thank’s for your help

Max

Hi Max,

Sadly not. R19 has more care about it, but also there, it might be not as prestine (depends on how picky one is, make your tests!) as the original was, mostly around texture borders, etc. R19 is much better in terms of UV-island protection. Anyway, R18 and R19 are night and day in comparison, to be clear: R19 has much better results.

Sorry, but it comes with the process in R18, some polygon groups that might be spread over the UV map are sometimes combined in a single new UV polygon, which can’t be partially divided over the image to get the old relation back.

All the best

Thanks for the reply, MAX.

I have recorded a little stress video, about what I think it is the worse case scenario. But you might also notice how powerful the new options are.

The pole caps on a sphere are certainly the most problematic texture area, as the complete texture width is squeezed into a nearly none existing space. Full width into a point, to say it extremely. So, it shows there the most. Again, stress test. If that area would have been normally textured it would be much-much better

Here is the clip, download it for a better viewing experience.

Thanks a lot, Max, very nice of you.

Let me know if there is anything else, I’m happy to look into it.
