Re: how to interpret the absorption depth value

I think you found a bug in BlendLuxCore. It is caused by the world scale. If I set world scale to 1 and scale everything to have the values you used, it works correctly. I have the feeling that this is the easiest way to find bugs: change worldscale and then test a few things, and boom you found a b...

Re: Denoised output

By the way, here is the reason why I implemented it this way: Consider what would happen if the denoised image should appear instead of the noisy image in the "Combined" pass. There are a few possibilities: Show the noisy image until the denoiser is run for the first time, then show the denoised ima...

Re: Denoised output

Can you be more precise?
What do you want to achieve?

You can use the DENOISED output like any other color output - view it with a viewer node, save it to disk with a file output node, or mix it through some crazy node setup.

Re: Caustics / Dispersion of Light

It works with any light, but you need a tight beam of nearly parallel light rays for a result like in the image you linked. If you want to use a sun light, you can do it like Newton and let the sun shine into a room through a tiny hole. (and combine this with the lightshaft setup I posted above, so ...

Re: Caustics / Dispersion of Light

It is really hard to guess what is going wrong without the .blend or at least a few screenshots of the scene and settings. And obviously a rendered image would be good. Also I do not understand which kind of scences 'luxcoreui' supports or if there is a way to convert my blender scene. luxcoreui is ...

Re: Caustics / Dispersion of Light

Have you raised the "Dispersion" value of the glass node?
You will also have to use "Bidir" as engine and "Metropolis" as sampler to get noise free caustics in a reasonable time.

Re: medieval UK coin

In that case I might be misinterpreting something.

Re: medieval UK coin

From what you've shown so far I like this one best: download/file.php?id=1285&mode=view
However it seems like the polygons from sculpting are still visible, you probably have to subdivide further and smooth it a bit (e.g. with dyntopo and smooth brush).
