Re: Luxcore is very slow and freezes

Here, it feels as snappy as before.
Latest commits from today (LuxCore 2bc28dca8, BlendLuxCore 9f3932b -- homebuild) on W10 with Blender 2.81a.

But IIRC, it's been mentioned that Blender is getting slower with every iteration until LTS or "everything nodes" (rewrite).

Re: ENV cache persistence

NOTE! Flickering is caused because the lighting in the scene is dynamic, while Persistence for PGI & Environment Caches are On! Specifically, HDRI intensity lowers just slightly over time to stay concurrent with the sun setting down (as can be observed). I was expecting it, but was also hoping to be...

They be like " Unbiased to the bone! " :lol: Users can also fully utilize measured data. Not only IOR, but also BRDF (IIRC, same...
