Sounds like a great idea

I think that can already be done using SamplerDescriptors? https://github.com/bevyengine/bevy/blob/8106f770de2ae3c841651499e0637123d7ae6688/crates/bevy_render/src/texture/sampler_descriptor.rs

I'm not sure how to specify a SamplerDescriptor for a texture. if I am reading this code correctly, it seems like the sampler is being generated automatically with a From impl. it does seem like a SamplerDescriptor would be the right API for this

How about adding SamplerDescriptor to Texture as a member and grabbing it from there? The code that constructs a SamplerDescriptor from a Texture doesn't even use that texture.

Yup adding a SamplerDescriptor to Texture has been on my "mental to-do list" for awhile. I think that's the right approach.

In #747 I've moved the SamplerDescriptor and adjusted the GLTF loader.

Still, when loading a texture manually (not from a GLTF file), like it's done in the texture example, we'd still need to specify the sampler somehow. Of course, we could just keep it this way, initialized with default, and the user could still mutate it after loading.

@W4RH4WK sounds reasonable.

Atelier Assets (which we will eventually migrate to) allows you to specify per-asset configuration in a ".meta" file. I think we will eventually put the SamplerDescriptor config there for formats like png.

#747 largely resolves this problem, but I think we should probably hold off on closing this until we can do it for arbitrary texture files (aka using the ".meta" config in atelier assets)
