Strange color in piz-compressed exr envMap?

Questions

Hi,

I’m using equirectangular exr envMaps. But when the exr is piz-compressed, there’s a strange green-blue area on the map, which does not exist if the exr is not compressed. (They look the same with exrdisplay and there’s nothing strange on the piz-comporessed one.)

Piz compressed:

Not compressed:

It seems EXRLoader.js only supports PIZ_COMPRESSION and NO_COMPRESSION. Is there anyway I can keep the size small and get rid of the green-blue color?
Thank you very much!

I think it’s best to post this issue at github instead: https://github.com/mrdoob/three.js/issues

This could be a problem of EXRLoader.
