PBR Toolkit 1-2-3 Free 3D model

With this program, you can use nodes to convert mask textures from Unity to Unreal Engine or vice versa, extract the four channels of a mask and save them as separate textures, or generate a new mask with the channel configuration you want, convert a texture to a normal map, and more.

Texture Set Combiner Included

It includes presets with node configurations for quick actions.

The entire program is designed to be fast and easy, without delays or complications.

Please contact me if you encounter any errors or problems. I personally use it to streamline my modeling and texturing work and to fix small details or errors with masks, so I'm constantly discovering new features or encountering unexpected bugs.
