Description

Issue 3 in the forum post

On WebGL, we get a crash once we enable point clouds:

Invoking error handler due to TypeError: Cannot read properties of undefined (reading ‘explicitUniformLocations’), at WebGL.framework.js.gz

It is mentioned in that blog post that point clouds are not supported for WebGL. However, I think it should not crash even if it does not render anything.

I was hoping that enabling attenuation affects these bugs in a positive way, but I don’t know.
