super stuck - the maya Uv grid size seems to stop at 1024 - you can't move the slider up anymore, also it doesn't seem to do anything visibly noticeable to the grid.
I'm texturing my model in substance painter and the current uv grid size is too small for the 4k textures substance painter applies. Everything else is fine but because the stone base of my mesh has a lot of surface area it hasn't got enough room to spread out in the default maya UV grid - so textures look blurred and low res when applied.
