Just now starting to learn the basics with normal maps and how to use them in other programs. My question is in the normal map options in the MM exporter should I select both tangent and adaptive? Also in the options for sub D level should I set it to my tools max sub D level, I.E my tool has 5 sub D levels so should I set the normal map sub D level to 5?
For the subdivision level, leave that at 1 unless for some reason you are using a mesh exported from a higher subdivision level in your render application.
Whether you use Tangent or not will depend on the requirements of your render application. I’d try with Adaptive off first - turning it on will increase the time taken to generate the maps.
