Title: Problem with caustics
Post by: mrsalomao1 on 2023-04-30, 01:28:11
Can someone please tell me what's going on? I'm using corona sun with intensity .05 (I've tested increasing it to 1.0), I've tested Hdri (several).

I'm using noise (I've already tested increasing and decreasing the height and scale) and turbo smooth.

What can it be? The caustics of the water are of a horrible quality (it seems faceted) and besides it has many fireflyes.

Somebody help me, please!

Hi,

What version of Corona you are currently using? I would recommend using the latest version which is Corona 9 HF 1 (at present) and also if you can please try using the Corona 10 DB version as there were some nice caustic improvements. You can download Corona 10 DB from here: https://forum.corona-renderer.com/index.php?topic=38385.0

Also, I would suggest you go through our informative and detailed helpdesk articles as they can give you enough insight on how to effectively work with Caustics in Corona.

Note: The daily builds are the newest, experimental versions of Corona Renderer intended mainly for testing purposes and to showcase the recently added features. They contain the latest bug fixes but are not guaranteed to be stable, and in some cases can even damage scene files.
