Light changes for Blender 2.80

The exporter is now running for the most part in Blender 2.80. Wildly un-tested. I have come across major differences in lights. Looks like we are going to lose some capabilities.

Here is the lights in 2.79:
lamp-279

  • You will notice that the Hemi type is now missing. Not sure what to do about that. Maybe use “Area” (which is what happened to an “Area” in 2.79), but that really sucks from a documentation standpoint.

  • Also, the “This Layer Only” check is gone. No real answer unless, we add our own “This Collection Only” check. Not going to do that, for now.

  • No “Diffuse” check. Probably no great loss. Who needs specular only lights?

  • Specular is now a 0-1. This is multiplied to the color, so here an actual improvement in capabilities.

  • Energy (intensity in BJS) is no no longer 0-1, and no real upper bound. I have no idea what to do, but something must be done. ANY IDEAS???

Here is 2.80, as of 11/27/18:
light-280

For energy we do have the same concept for lights in PBR mode:Babylon.js Documentation

As I said over on another thread,-I don’t envy the task you are facing. And from what I gather somethings may get changed back. And this version of 2.80 is not the final release.

That layers and collections business was one of the things that bothered me. But good luck Jeff - if anyone can figure it out, you can.
