Animations always (!) flickering

[BenGreyjoy]

Hello,

i have the problem since is started with Luxcore for Blender, about 6 weeks ago:

in that time i made about 6 different animations with different settings and never got a flicker-free animation.
as a base scene i used the "Luxcore 2.1 benchmark test" scene from your website..

the flickering is horrible and i don´t find any useful idea to get rid of it, nor is it possible to reduce the flickering with any plugins.
some frames are way darker, some frames very bright, all other frames have a flickering like light sources are flying around with high speed.

though, i have always two error messages:

1. "Slow custom normal export in this Blender version (took 0.7 s)"
2. "The scene contains a lot of light sources (360074), performance might suffer (each triangle of a meshlight counts as a separate light)"

regarding 2.: any emissions of any materials are tuned off or set to black, i have only two light sources.

I use Cycles materials and Luxcore materials in the scene.

P.S. unfortunately it´s not possible to register to your forum so i have to ask here,
hope you can give me some help

thank you in advance
