Hi I am having trouble getting the Equirect HRD to work inside the threejs editor. When I load an HDR image it looks very pixelated. Also on play the image does not render at all.

RGBE is not monotonic in its encoded state so you can’t use built-in texture filtering.
There are several issue at GitHub tracking the state of texture features:
