I have two 3D laser scanned files of a complex object I want to model. One has a "medium resolution" and I used it as a reference to create the model with Blender. Everything's fine. Now I have to attach the textures, however I would like to use the pictures at full resolution.
For the high resolution, they gave me a .obj, .mtl and several .jpg files. The problem is that this .obj file is over 5 GB, and there's no way to import it into Blender as 32 GB of RAM is insufficient. I've already tried all the suggestions from previous similar questions (like this) with no results. I tried to convert it to ABC but still doesn't import it. I also tried other programs like Open3D, but again no 32 GB of memory is insufficient.
However, I only want the textures to paste them into my model, not the full obj model (because I used the smaller one as a reference). Is there a way to extract (in a decent understandable format) the textures from the obj/mtl? Because the current .jpg files contains random parts of the object and it looks very difficult manually pick them (example of a texture follows).
Manually extracting the textures of the object from there looks very difficult...
