Substance Painter will only make map sizes of 128 ,256 ,512 ,1024 ,2048 ,4096.sqared.

zBrush has a slider so you can make any squared size from 256 to 8192.but there squared. zBrush has 512 ,1024 ,2048 ,4096 tabs. I don't know if you can make a unsquared map in Z.

Blender you can make unsquared UV Map of 50x10,000. Have no idea how Blender treats a UV Map that's 50x10,000.

I don't really care to learn all the tech part about PC's ,3Dcards etc etc. I never needed to learn how to make oil paint. I guess different App's have different rules. but I do know 1024 ,2048 ,4096 will work in any app and since it's what the Pro's use .I can't go wrong.

Yes there are some very nice diffuse ,bumps ,specular maps for DAZ Poser. but where are all the other maps ? I just don't see the material room pushed to the limit that often. You can always tell a DAZ Poser render. Why is that ?
