Unwrap settings is limited with numbers of polygons

Hi,

I have been facing a problem for several days.
I have a model that has about 500 million polygons after alignment.
So I divide it until it's only 60,000 polygons.

And when I want to unwrap the model and texture it, I get an error:

"Could not meet the unwrap requirements. Please increase the maximal texture count or the maximal texture resolution" while I'm in Fixed texel size !

Here are my parameters :

By trying with another model with 1 million polygons, however, it works well.

I also tried reprojection but the quality is still bad on the 60,000 polygon model.

I have the impression that the fewer polygons there are, the lower the quality of the texture is.

Need help please.

Thanks

  Hello,

  I tried to reproduce the problem on a similar-sized dataset but I was unable to reproduce it. Please contact us through a technical inquiry on this website so we can file it a closely watch progress with the issue:

  It would really help us if you could share the dataset with us so we can reproduce the problem.

  Thanks for your reply.

  I just send you a form by your link.

  You will find the entire project to download and more infos on the steps to produce the issue.

  Have a nice day,

  I have the same issue since I use fixed texel size. I had it for maybe 10/15 models at least.

  Only solution I found is to switch to maximum texture count and to be limited to less than 100% texture quality.

  I tried your solution, and i didn't get the error but the texture quality is very bad.

  Here is a screen of the unwrap parameters and the result on the model :

  As you can see, i put a limit of 500 maximal texture count, but it only make 10 textures...

  Did you use texture reprojection or simple texturing?

  When you did the texture on the 1M mesh, did you get 100% quality with 4k texture ? It might help to increase texture size to 8k if it's not.

  I noticed less of the " could not meet (...) requirement " when reprojecting texture on a simplified mesh with 8k fixed texel size unwrap than with 4k textures.

  But anyway, this is an issue I hope will be rectified soon as you could be limited to 60/70% texture quality whatever you do.

  Texture reprojection is also limited, it reduce quality when reprojecting.

  It looks that quality percent is relative to poly count.

  I can get approximately 20% quality with 16k textures, but i need 4k textures.

  I just faced the same problem in a simplified model. One workaround that worked for me was to use adaptive unwrap once. After that I was able to use again all unwrap options. It seems like a bug for me.
