Reducing the texture UV map file size
Hi all,
I am trying to reduce the file size of the UV mapping (xyz_u1_v1.png) that comes with exporting a mesh.
The original model has 1.7 million triangles and after I export the mesh the UV map is 89 mb's
After I run simplification down to 40,000 triangles, unwrap the model, retexture and then export the mesh again the UV map is 59mb's
Does anyone know of a way to get the UV map png size down even further to say 10mb's?
Thank you in advance!

5 minutes after I posted this I figured out one technique to getting that file size down to under 10mb.
Here's how I did it
1) Reconstruction > Unwrap
2) Changed "Maximal texture resolution" from 8192 x 8192 to 4096 x 4096
I hope this helps someone else!
Any additional tips are always welcomed :) -
You can always just open the texture file in Photoshop and resize it there.
You could even save it as a lossy texture format, like a jpg, provided you open the supplied *.mtl file in a text formatting program and change the texture path from "xyztexture.png" to "xyztexture.jpg".
The last step is important, otherwise the model will just use, or ask for the original texture file.
