I made a few scans using Photoscan and they look decent. They are however made out of hundreds of thousands polys and I wanted to retopologize them.
To do that I took the obj file which was produced by Photoscan and processed in Instant Meshes. For me it did fantastic job. Reduced number of faces with preserved shapes. This is what I was looking for.
I would like to apply a textures to the low poly model. I do have a texture map exported with obj and mtl files, but I do not know how to transfer it to Instant Meshes output obj.
This is how high poly (400k faces) model looks like:
And this is low poly (53k) modification:
Instant meshes has done fantastic job as I said so I want to push it further. So I would like to use existing textures (visible on low poly model), bake them on low poly version, and retouch it a bit to look even better.
Can somebody give me tips what to do next? Which functions, modifiers etc should I use?
