Interesting scene composition. I like the scene with lens array.
Some observations. There seems still to be a lot of chromatic noise in the shadow regions.
The bidirectional path tracer may be better suited for this type of scene with caustics.
Also the sharp ring-shaped shadows look strange. One would expect more even intensity transitions from convex shaped lenses lit by a large area light.

Thank you much for your feedback, Mango3.

The composition is one of my reasons to choose it for the Mediabook in Finised Work. Another reason is, the picture shows what is at least possible with LuxCoreRenders' openCL/GPU path render in regard to caustics. ("Concentration of light, especially sunlight, can burn. The word caustic, in fact, comes from the Greek καυστός, burnt, via the Latin causticus, burning", wikipedia, 28.10.2018).

Indeed, there is a lot of chromatic noise in the picture, but there also is in pictures rendered with BiDir, see viewtopic.php?f=2&t=576&start=30#p6987 and similar posts.


I am not sure, if I understand what you expect from an area light covering the area of lens array. These lenses (convex) focus light, there must be shadow somewhere because of 'collected' light. The surface in the the picture is plane, diffuse (matte) but even, a simple artifical surface with no hight. It does not behave like paper, or something we know based on real world experiences.

Hi FarbigeWelt,

I made myself quickly a similar test scene and the sharp intensity transitions of the shadow borders are indeed correct.
It was just my first (wrong) intuition that the shadows look overly sharp.

Now I saw that in your Different Works in Progress thread you posted comparison pictures with bidir-cpu and path-pgu.
Always interesting to see comparison render of the different light transport methods. Nice work.

For difficult caustics Stochastic Progressive Photon Mapping is a good algorithm (old Lux Classic had it).

If you don't mind, how does the image look before denoising? 2100 samples is quite a lot

I have to check if I saved the raw too. There was some noise left here and there, but much less than with all lights enabled, especially the blue laser leads intentional to lot of ‚noise‘ because of the rough metal surface of the sphere to the left.

Those are cool renders!
Looks like AI cities after humanity gone extinct 8-)

You could do animations by blending/fading between different lightings as with the first two renders.
Make single buildings appear and disappear and so on.

Thank you much!

Was not my intend to give this impression. However the material to create this building is not yet invented it is quasi transparent like opacified glass.
