LuxCoreRender Forums

I am probably not the best to talk about render settings, but caustics will be much faster using Light tracing. Metropolis isn't worth it anymore and is usually worse than Sobol. I like using Random as I get better denoising result, that OpenCL Sobol has a weird stretched pattern that doesn't denois...

Looks promising!

Any specific reason you are using Metropolis?

Thanks Dade!

CPU and OpenCL, I tried both.

Hi there,

I'm noticing a difference between the viewport and the final render. I am not using clamping, there is nothing done in Compositing, so I'm not sure why it looks like it's clamping or applying a different tonemap.\
I attached the scene.

I can't talk about the Clamping as I am not sure how it works. About your light brightness, you need to not forget about the inverse square law, that makes the brightness decay with distance. The brightness is also divided by Pi because we assume the emission is calculated per steradian (this is onl...

What are exactly your settings ? Sensitivity, exposure, fstop ? F/1.0, Shutter speed 1s, ISO 100 which corresponds to EV100 0. If it helps, 2.5 lux results in "proper" exposure for EV0. Meaning, I guess, middle gray is middle gray? Maybe this is the confusion here? When we say EV 0 corres...

@Dade, can you please check the Camera exposure math to see if everything is correct? In Unreal, here is a 1 candela point light placed 1 meter above a white floor: UE4Editor_yK6hXgKXuT.png As you can see it reads 1 lux, everything is exposed with a manual EV of 0. This is in 4.25 without using the ...

I wanted to make sure there was no wrong information staying on the forum as I wrote some confusing things yesterday. If LuxCore tonemapping is off, the output is luminance (cd/m2) and can be saved as EXR and HDR format. With the next version of Photographer (3.x), you will be able to visualize came...

Is there an option somewhere in the tons of Blender menus that allows me to read those raw values? I really don't see an option there to read the numbers. In the render settings, under Color management: blender_tPGsEy9BiV.png Then disable LuxCore tonemapper in the camera: blender_2aPO9n4hoK.png In ...
