Plugins: Consider plugin that uses / enables use of BatchedMesh

**Options** ```js { instanceCount, vertexCount, indexCount, expansionPercent, maxExpansionCount, // possibly just inherit? textureSize, generateMipmaps, wrapping, etc, material, } ```

Suggestion: Separate "overriding the render loop" from "renderPriority" in useFrame

@CodyJasonBennett > this is something we have designed for v10 If there's a brief write up or anything on how this would work I can take a look to see...

Respecting Batched Mesh Instance Visibility in three-gpu-pathtracer

Unfortunately neither InstancedMesh nor BatchedMesh are directly supported by the project. Generally the way the path tracer works is all geometry is merged into a giant monolithic mesh for rendering...

Hair material(s)?

There's currently no special support for hair rendering. If there are good articles on the topic feel free to leave them here for discussion, though.

R3F Components: Consider adding a screen-space ruler component

Terriajs implements this [here](https://github.com/TerriaJS/terriajs/blob/0aea1b6eb566f4bc0edf971628b406d065a9ab91/lib/ReactViews/Map/BottomBar/DistanceLegend.tsx#L91) and chooses the two sibling pixels at the bottom center of the screen to determine lat / lon and measure distance between the two points using...

three-gpu-pathtracer hardcodes first UV Map for materials, even if that's the wrong one

Hi @FrostKiwi! Thanks for the report - when the pathtracer was written three.js did not support setting custom UV channels per texture so the code is written to support the...

Add atmospheric scattering shader

Add GGX multiscatter compensation with Cycles albedo method

Thanks! I'll take a look at this more in depth when I have a chance. There has been some pretty bad energy loss for metallic materials, unfortunately. Do you mind...

Add GGX multiscatter compensation with Cycles albedo method

Thanks - I'll have to take a deeper look at this next week. The reason #349 wasn't merged is because it was causing some models to render as too bright...

[WIP] Webgpu pathtracer prototype

Amazing work! Thanks for putting the time in. In terms of getting an initial version merged I think these are some good goals. I think this should help get the...
