MIME type validation for webp seems to be missing.

Tom Goldsmith

I get "TEXTURE_INVALID_IMAGE_MIME_TYPE" and "Invalid MIME type 'image/webp' for the texture source. Valid MIME types are ('image/jpeg', 'image/png')." The official GLTF Validator gives a valid response for the same asset.

I'm not able to reproduce this issue, using a model with the EXT_texture_webp extension, created by:
gltf-transform webp in.glb out.glb
Does your model use the EXT_texture_webp extension, and are you able to share that?

Don McCurdy Yes try this one: https://drive.google.com/file/d/1n-2mLCA50Zr-hlQleLghj32lpgf0Y1i5/view?usp=sharing

Tom Goldsmith hm, ok thanks! I agree this file looks valid, I'm not sure why one WebP file would pass and one would fail yet. Will look into this.

Don McCurdy Thank you, and let me know if there is anything I can do to help!
