Submission Guidelines - Textures
Last Updated: September 6, 2025
The Texture Format
Textures should be submitted in the PNG format. This is because .png is a lossless format. If a texture’s native format is .JPG, these will be acceptable within a ZIP submission. You must include a note explaining why you included JPG files, however.
Texture Transparencies
If a texture has transparencies, you usually don't remove them, as doing so can make applying the transparencies more difficult. The only time where you may need to remove a transparency is if it obstructs the diffuse texture at all. Some game engines tend to use the alpha channel of a texture image as a specular map, so splitting the alpha channel off of the diffuse texture will provide both the diffuse and specular maps properly.
