In the 3D plotting options there is an option to set the texture map size to either small (128x128), medium (256x256), large (512x512) or unlimited. Is there a way to make this user defined? Like if I wanted something between large and unlimited.

I have a plot that if I use large it comes out to about 4MB but if I use unlimited, it comes out to over 80MB, I would like some setting in between.

Especially needed for publishing reality meshes.
