How to generate a single texture file, instead of many separate texture files? #77

How to generate a single texture file, instead of many separate texture files? I wanna fix the model in some 3d editing software, like zbrush, then regenerate the uv, but I only know how to do it with a single texture file. Can "texrecon" produce a single texture file which contains all the textures in one big png?

@andre-schulz has made adjustments to the texture atlas generation such that it should produce a single texture atlas. Please refer to the single-texture-atlas branch of his fork.

thanks for the quick reply!

This fork doesnt work anymore due to the recent API changes:

How did you guys get it to compile?

Ok, I just integrated this particular commit and it seems to generate single texture files

FYI, I've updated my fork of mvs-texturing with the latest changes. It should compile without errors now.

Can I check..if my texture/image that is being sampled is larger than 1024*1024, does your code still make sure that the texture file gets expanded accordingly?

nmoehrle commented 6 years ago

@andre-schulz can you answer that?
