About export materials #2

Hi!

Thank you for this great work!

I'm a little confused about export materials. why should repeat uvs to a neighborhood? and is the basic idea to use gaussian as a weight to sum up repeat values? https://github.com/Kai-46/IRON/blob/ced411ed34e192cc620883a792e24127dbb2f654/models/export_materials.py#L95

Yes, you are right: it's Gaussian-kernel-based splatting to avoid small holes in the texture images.
