Fixed gray texture on export.

Browse Source 
Fixed gray texture on export bug, it was caused by the texture scale function (during upscaling), right now it's required to have the texture dimensions be a power of 2 width/height.
Optional OBJ/PNG/sprite export options.
Chanaged readme.
TODO: Cleanup export code. Make proper scale options (bilinear & point).

# MA_TextureAtlasser
Texture atlas creator for Unity
You can combine textures and/or remap the UV’s for the 3D models.
By having full control over the size and position of the textures that are being placed in the atlas you will never stand for surprises when exporting. This will cost some more time than auto-generating your texture atlases but you know whats going on and which models/textures are getting priority.

By having full control over the size and position of the textures that are being placed in the atlas you will never stand for surprises when exporting. This will cost some more time than auto-generating your texture atlases but you know whats going on and which models/textures are getting priority. The tool can also be used to make 2D sprite sheets.
- Combine textures/sprites.
- Automatically adjusts the UV's of the assigned meshes to match the new texture atlas.
- Exports meshes as OBJ.
- Exports texture atlas as PNG.
- Exports texture atlas as a (sliced) sprite sheet.
