I modelled the optics to be physically correct. It has a small LED and a TIR (Total Internal Reflection) lens.
BiDir Metropolis (2850 samples):
Hybrid (also on CPU, 4470 samples):
Both were denoised with OIDN.
Hybrid seems to be faster (in convergence), but unfortunately, there are significant differences between the result images.

Re: Flashlight with TIR lens
Good modelling and nice setting but the inhomogeneous light cone looks weird (in both versions).
Sorry to be of no help but I never attempted precise and correct settings like this.
I'd try to get away with an IES file ...

Fancy! Looks like a merchandise material from the new Star Wars... everybody has one but this one is white XXL
Re: Flashlight with TIR lens
Thanks, and you're right... I wanted some variance in the lightbeam, so I used heterogeneous volume with a noise pattern, but It didn't become the best.epilectrolytics wrote: ↑Sat Jul 06, 2019 8:54 pm Good modelling and nice setting but the inhomogeneous light cone looks weird (in both versions).

Very nice flashlight(Luxcore powered lighting).
Re: Flashlight with TIR lens
What texture did you use?
I would try a larger scale clouds texture, or maybe even a smoke simulation.
Re: Flashlight with TIR lens
If I remember correctly it was Improved Perlin.
I'll get back to it after I buy a faster PC. On my current old Core i5 it was painfully slow to test the settings.
