Simplest Environment Texture for AO

Questions

I have a GLTF model that has Ambient Occlusion baked into it. I read that you must set an environment texture on the scene in order for the AO to appear. I would like the AO to appear but I don’t need the environment texture at all.

I am wondering is there a trivially simple CubeTexture I can use as the environment texture such that AO appears but I don’t have to load a large .env file over the web?

The AO is also used to modulate the ambient color, so if you have an ambient color which is not black you should see your AO somehow.

Note that for the best results with PBR materials you really should use an environment file… Those files are not necessarily large, for eg environment.env in the playground textures/ directory is 342 ko only.
