I'm trying to edit beetle blocks to allow babylon textures. Do I need to convert the costumes to a file or something or can I convert it to PNG? Also when I get it to work how can I import it into a normal project?
Those are the same thing...
Also, how are you adding textures? We don't know how to help, if you don't tell us how you're adding textures.
in Babylon you can use material.defuseTexture = BABYLON.Texture("folder/image.png")
the problom is the URL for the image.
The url can probably just be a data url, which you can get from a costume just by running normalizeCanvas(costume.contents).toDataURL('image/png')
(if it's a bitmap, if it's an svg, that's a bit different).
