playing with caustics

[epilectrolytics]

Bidir, took two days to render.
Denoising and color correction in Photoshop (don't get OptiX deoiser to work with Bidir).
Resolution and frame rate doubled in DaVinci Resolve.

Great result!
Some absorption color would be cool, to see which caustics are refracted and which are reflected

(don't get OptiX deoiser to work with Bidir)

It was only trained on unidirectional pathtracer input, so it doesn't work with Bidir.

Thanks!
I tried of course but the noise was worse and I didn't want a week long render...

It is a real beauty

Thanks again!

So here is a quick and dirty dispersion render:

The description of the D-noise plug-in suggests that everything, even photos could be denoised.
I didn't try because that plugin always lost the binary path after rebooting so I installed another.
But with better Bidir denoising rendering animated volumetric caustics with dispersion would be possible (on my Ryzen octocore).

EDIT: Better render.

It won't recognize the noise and denoising photos works only partially(if you can even say it is working)

here's the thing, it knows how montecarlo pathtracing noise looks and how to remove it.
Noise from photography is very different although the algorithm might confuse some of it as pathtracing noise so it might partially work.
BiDir noise is also different cause afaik it also includes lighttracing and who knows in what other differences.
It is actually not that hard to break the ai denoiser since it doesn't use additional passes, just enable chromatic abberation in camera settings and try to denoise.

Chromatic aberration is done after the denoiser so it can not have any effect (or BlendLuxCore builds the image pipeline in the wrong order )

but we were talking about the optix denoiser.

Bidirmetro as usual, slowed down 50% with simple frame blending.

Very cool, keep them coming.
I'd really like to make a short LuxCore demo reel at some point, but people don't post videos very often (which I can totally understand).
However, your work gives me hope
