Parallax maps question
Posted: 13 Nov 2018, 02:42
A mod just arrived, and not a day too late: https://www.nexusmods.com/morrowind/mods/45399
Basically, the project is working on combining all the textures of the different sets into one big texture for each theme (like hlaalu for example) and modify the UV maps to work with these textures. This is something I've wanted to do for years but never had the time to do.
So anyway, this brings up the question of normal maps and more specifically, parallax maps. If I don't want to have parallax effect in a texture that still has a _nh.dds file with an alpha channel in it, should the alpha channel for that part be pitch black or pure white or somewhere in between? Because if I want some of the textures of the Velothi set to have parallax mapping, I need to have a height map for the entire set.
