Hi all, I’m having this strange issue where a scene which was rendering water caustics inside Corona 5 is now having issues with Corona 6
I’ve noted a few variables where if I isolate the pool (pictured) it renders normally after 2 minutes. But when the full scene is loaded, it can sit there for half an hour without any caustics generated, or very tiny dots scattered around the frame (also pictured).
The scene here has glass which doesn’t have caustics ticked, and that’s pretty much it. Deleting all the glass also doesn’t change things. Scene complexity isn’t high at all, not that it should matter as it rendered just fine with Corona 5 - same computer, same render times.
Are there any dev mode settings I can tweak to fix this up? Thanks in advance
It would be best if we could take a look at your scene and investigate any possible setup issues, could you please archive your scene and upload it using our private uploader?
I’ve uploaded the scene via the link and checked it one last time to see the issue persists. I’ve also tried merging the scene into a fresh max and switched the renderer to scanline and then back to corona to reset the settings. Hopefully that is what you meant by a reset.
This is a pretty curious issue, I am afraid I won’t be much of a help for the moment since I really can’t exactly pinpoint why this is happening. I’ve reported it to the devs for further assessment. I was also able to recreate it in a new scene so it’s not scene-specific. Lastly, removing reflection from all glass elements does help with the caustic generation inside the pool (nice naming of water btw) but it’s not an optimal solution.
So please stay tuned for further updates on the issue.
