It’s no problem to convert EXR to HDR in Gimp. The thing is, that Verge3D users should be made aware that the native Blender 2.8 background images like all other EXR images should be converted first to HDR before they can use them.
What about the light settings mentioned in the first part of this test report. Has the difference in lighting between Eevee (darker) and the V3D result (lighter) to do with Blenders 2.8 Filmic color management? Can Filmic be implemented in WebGL?
That would be great!
With my light settings in Blender and the post-process settings in Puzzles, I get pretty good results! It is an example of how things can be tweaked for now.
I hope the above little beta test examples give some useful information.
Good luck with making Verge3D super cool!
