I am working o a model made of 8000 photos. The model has 50M triangles.
Now each time I want to process 10 textures it takes ages, because first it wants to do it on CPU instead of GPU. Even if I click processing in the background and it closes the model, for some reason it does not have enough momory to do it anyway. The part that takes ages is blending textures, so after UVs are done and I do not udnerstand why the size of the model matters at this stage. Creating 10 textures on a 3-5M triangles takes only a few minutes.
A huge part of the process is "Estimating Quality". Is is the same as the option of Estimating Image Quality? I ran Estimate Image Quality on all images just before texture generation and it took only around 35 minutes. Did not help though. Now at the stage of blending textures it is estimating quality again. It has run for the last 6 hours and so fat 72% done.
