LightTracing BlendLuxCore 2.3 vs. BlendLuxCore 2.4 ?

Post by denon100 » Mon May 18, 2020 1:24 pm

Hi,
is this behavior normal in BlendLuxCore 2.4 with LightTracing?
If the LightTracing is on or off, the material colors change.
Have otherwise made no changes.
This does not happen with BlendLuxCore 2.3.

thank you

Are you using automatic tonemapping?
Can you upload the scene?

It is a view port rendering with and without light tracing (PATHCPU Vs RTPATHCPU) :?: Do you get the same results in final rendering (i.e. PATHCPU Vs. PATHCPU) ?

final rendering identical to viewport rendering :!:

by the way, everything works with the Disney material :?
as in BlendLuxCore 2.3

I have the same problem with you denon100.If i change the plane material to disney or glossy or metal with roughness included to Light tracing glossiness threshold it works ok.

It was a bug in MIS code when rendering env. light sources with light tracing. I should have fixed the problem.
