This extension will allow you to add normal maps to 3D objects in your game. For those unfamiliar, A normal map is a texture that tells light which way a surface is “facing,” so flat art can look bumpy, carved, or detailed without adding extra geometry.
Download the Normalmap3D extension here.
If you need a normal map, you can create them for free at NormalMap-Online.
