If .env Environments and textures could be packed within a .babylon file without external references, this would solve all of my current issues. Can this be made a reality? Thank you

No worries, you’re in the right place! The .babylon serializer supports serializing textures, so if there’s an .env not being serialized, that sounds like a bug. Let me have a look :slight_smile:

Ack, it’s not exactly a bug-- it would be a new feature. Only the Texture class can encode its image data in the Babylon serializer, not the CubeTexture class or its relatives. Before I go invent a new mime type to base64-encode .env files, maybe @PatrickRyan knows a better way to pack these textur…

Packing textures in the GLB works… Maybe it would be easier to allow use of PNGs or JPGs in equirectangular layout as the environment and IBL texture..? Just grasping at straws here ;D

@alexchuber and @staub , an .env file is an edge case here when using the term “embed textures” because it’s not technically a texture anymore. It’s a Babylon-specific cube map with a special encoding to retain HDR values from an IBL in a very small file. Support for packing an .env in a glTF won’t g…
