Problem with correct Exposure in Luxcore

Post by syhrdrjrt »

Unfortunately i can not upload this scene because it is too big.
These two scenes have the identical background, are both lit by a sun with physically correct brightness, have a similar material applied to the scene, no clamping and have the same number of light bounces.

CYCLES:
In Cycles I use an addon to set the camera to a suitable exposure for a sunny day :

This addon changes the exposure in the Color Management tab:

LUXCORE:
If I then try to render this scene with the same exposure setting using Luxcore I get this completely different result:
(apparently Luxcore cannot process this setting correctly, or at least not in the same way cylces does?)

if I then set this exposure in the Color Managment tab back to zero and instead use the Luxcore Camera Tonemapper with the same camera settings for a sunny day, I get this result:

Which is still very different from the result in cycles. Why?

When you h1ve too large scene file you make a simplified version of it with all settings and upload it.

Also note
If you're simply switching between Cycles & LuxCore, not everything works OoB > Cycles Scene Reader (features),
so inconsistencies are expected.

Oh, also, looks like you have some stuff there which is visible in rendering but not in viewport. :?
