Dade, does this feature need some specific settings with BlendLuxCore?

Now that the daily build has the 2.4 branch, I'd like to test it.
Thanks for reminding me, I have added BlendLuxCore support.

Please, add a way to stop a cache calculation.
With just a quality setting, it's very difficult to forecast how much heavy will be the cache calculation.

So, to cut away every doubt, a responsive way to stop it is more than welcome.

Look like Env_Cache is broken in luxcore 2.4 master :

Result are noisier and darker while using Envcache.

Just trying to reproduce the behaviour with a simpler scene.

Can you upload the scene? (stripped down if necessary)

Can someone test and confirm on Windows 10. Just wait for that to make my video comparison.

Most noise in this scene comes from indirect light, which is not accelerated by env. light cache (use PhotonGI instead).

This is the result when I set max bounces to 1 (only render direct light):
