After installing rc5 black pixels are still appearing in the caustics pass. There's no option to disable caustics adaptivity. Any way to fix this?

You need to enable the development / experimental stuff rollout first (see my post above), and then you will find the adaptivity setting (see screenshot).

Silly me, I was checking the dev settings in a previous version. I see the checkbox is now visible after installing RC5. I will check if this fixes it.

Yeah, the devel rollout sometimes gets hidden when re-installing Corona or updating to a newer version.

Can verify that turning off Caustics Adaptivity does completely solve the problem. But it does indeed add quite a bit of extra render time to certain scenes, doubling it in some cases. Very much hoping this can be solved soon! (Maybe at the same time as a dedicated include/exclude list for Caustics Receive built into the CoronaMaterial....) :)

This is really good caustics from Otoy:

I have been thinking for a long time that if Corona remains proudly CPU based, it would be great to shift all sorts of secondary tasks to the GPU, for example, denoiser, caustics, bloom and glare, etc., it would be a really efficient use of resources, I understand how complicated this task is but maybe one day :D

I think that's the understatement of the year. That video is simply mind blowing.
I'm not Corona Team member. Everything i say, is my personal opinion only.

That is very impressive although it's a super duper simple scene. I'd love to see it applied to a complex scene.

Hi Guys,

We implemented some changes to the caustics render elements in the last daily build. These should hopefully improve the include/exclude feature we implemented previously.

Quote
  • Caustics
    • Added the following options to caustic render element
      • Include direct - includes directly visible caustics in render element
      • Include reflected - includes caustics visible through reflection (and then possible following reflection/refractions)
      • Include refracted - includes caustics visible through refraction (and then possible following reflection/refractions)
      • Include GI - includes caustics visible through GI

I'm interested to hear your feedback on it. You can grab the build from here: https://forum.corona-renderer.com/index.php?topic=33839.msg193564#msg193564

Thanks,

Rowan

These look really useful! Nice work guys. Will hopefully get a chance to test a DB soon to give these a go.

Cheers,
