I could trace the this value (118 / 255) back to mentions of the norm ISO12232. Apparently the exposure of an 18% gray card shall lead to sRGB values of 118 after apoplying gamma 2.2, where (118/255)^2.2 approximately equals 0.18.
I did a test with Blenders default cube scene, rendered within ...

Dear LuxCoreRender community,
As many of you know, BountySource, our previous donation platform, went out of business in 2023. Since then, the project has lacked a reliable way for users, artists, and contributors to support ongoing development and maintenance efforts.

I don't have experience with the BakeCPU engine yet either, so unfortunately I can't give any specific advice on this topic.

Re: BiDir: Gap in Laser Beam wanders with Camera
It is not a new thing. I've also opened a GitHub Issue about it years ago:
https://github.com/LuxCoreRender/LuxCore/issues/216
I'm not sure what Dade referred to in there regarding this being fixed (no commits or anything were linked).
I'm aware of it, I would reopen that Issue if I can describe ...

Re: animation settings
It looks that I have solved the issue.
Very nice, thank you very much!
I'm currently working on another issue, but will try to test it later.
About sharing this fix, ideal at the moment would be to open a pull request on top of the branch "for_v2.11", the working branch for the next release ...

Re: Can't get rid of CUDA error in Blender
The python bindings of LuxCore, "pyluxcore", which are used by BlendLuxCore, install the CUDA runtime compiler through a python package. Currently that is the latest version of this:

Currently, this will install CUDA 12.9.

Your renders look to me as if Camera>Tonemapper applied somehow with different settings.
I will take this into account in the bug report.
The fact that my two attempts leading to different results during the first try (where the cache is computed, not loaded), would suggest that it indeed may ...
