Just a general question…
If I have a normal map that is lower resolution than the Albedo…will there be an issue with artifacts? I want to reduce the amount of memory the Materials are using…and I thought about this as a way to optimize the materials.
I would like to keep my Albedo at 2k…and reduce the normal and occlusion maps to 1k. They reduce from 5.3 MB down to 1.3 MB…which is huge. They still look very similar…but want to make sure I’m not doing anything that can cause visual issues.
It would make sense that what’s happening is your normal map just gets stretched out more than your texture so the visual result should be the same as if you had a low resolution normal map and upscaled it with software to match the resolution of your texture map.
So if it looks good I wouldn’t worry about it. It might just be that you don’t need a lot of details in your normal maps for how you’re using them.
Thanks for the reply. That makes total sense. I’ll reduce them down on a case by case basis.
