@kaosat-dev At first I tried to use a 10K triangles model but as it didn't render I downscaled to 5K, 3K, 2K then 1K. And after, I made another model with 2x more slices that this script was unable to render even with a 1K model, so I changed the script to make it render chunks of slices, and it was ok. I suppose it could work with higher resolutions models.
