Attached is a sequence of renderings (path tracing, no PhotonGI) with increasing total + specular depths.

I would still like to understand why I only start to see the SDS caustic with a depth setting (as set in the UI in blender) of (total = 3, diffuse = 1, glossy = 1, specular = 3) , whereas I ...

My very first question: are we talking of human cartilage ? Does the meniscus really act as glass material ? It sounds strange.


I am sorry, I should have made the setup more clear: Meniscus relates to the liquid phenomenon of wetting, so I use the term in this sense (i.e. not in the medical ...

Again, thank you for your reply!


If you set specular max. depth to 1, you will get a black mirror because you need at least 2 bounces to see something:

1) ray hits a specular surface;
2) secondary ray hits another surface (and it is seen in the first one).


I am curious: Why could I not ...

Dear Dade,

thank you for your quick reply!

However: If 1 is internally added , I would expect external reflection only when 0 is set in Blender for specular interactions? Instead, I see external reflections only if I set the setting to 2, which should then (adding 1 internally) correspond to a ...

Hello!

First of all: a big thank you to all developers and supporters for the developments and making LuxCoreRender opensource! It is a great tool also for scientists and it already helped me to investigate some interesting everyday optical phenomena (cf. "Wine glass caustic and halo analogies ...
