Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes I would like to understand the precision of the position and normal textures in the G-buffer. In pg, my camera’s max Z is 20000 and min Z is 0.1. I’m using the WebGPU…

Thanks for the repro, you need “filterable float” in your pg which needs to be requested at engine creation time, this will also imply going past the default webgpu limits: Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes …

I am wondering if the precision loss is due to the camera frustum being too large or having too many meshes in the scene.

in my project, console warning. [image]

I think I found the problem, It is caused by the camera coordinate offset being too large or negative. but I don’t know how to fix it. [image] other spot light radius image: [image]

I would like to understand why this happens. Is it caused by negative coordinates? Or is it because the texture data type is unsigned float?

It is because moving too far from the origin creating precision issues on the depth buffer

Besides using a floating origin camera, are there any other solutions to address this issue? My scene contains a large number of meshes (around 300), and I am concerned about potential performance issues if the meshes are moved frequently with a floating origin camera.

Why do you have backfaceCulling = false for the tunnel and the road and why are those meshes created as doublesided? For me it looks like the opposite faces of the meshes are z-figthing.
