I'm using Marmoset Toolbag as my primary texturing tool and I am very pleased with it. However, since I make game assets, I want to experiment with making my trim sheets in a rectangular textures rather than square as 1024x2048 to save on the number of texture files used.
I attempted to set this up when baking, but all that I accomplished was one half of the bake that would be 1024x1024 squished/stretched in one ones axis so the one half of what I wanted to bake was distorted into 1024x2048.
Is this something that Marmoset is capable of? If so, is it perhaps that I didn't set up the UVs or something correctly in blender prior to export?
Also, is there a way to change the orientation of the green channel of the normal map? When I export my textures to either Blender or Unity, I end up having to flip the green channel, but it would be nice to know if I can flip it within Marmoset. I assume you can, but I'm probably just ignorant.
I've attached a couple of screenshots to illustrate what I mean.
