Bitmap2Material 2.1

FOR USE IN UNITY3D PRO ENGINE

Bitmap2Material is an incredibly powerful tool that helps you generate full, seamlessly tiling materials (normal map, height map, specular, etc.) from any bitmap image, right within your favorite DCC tool and game engine.

Substances being fully supported in Unity 3D and UDK/UE3, B2M can be used in your game engines with the Pro license.
Bitmap2Material used in the context of those game engine offers two great benefits:

It saves production time by all the material maps (normal map, height map, specular map...) directly in the Editor.

It reduces your game size by generating all output maps of these materials on the client side.

Bitmap2Material offers a dedicated, optimized path for game developers to generate their material maps (normal, specular, height, etc.) directly onto their target device at runtime, hence dramatically reducing their games' client size.
