I'm sorry to post this without any evidence, but I'm just reaching out in case this is a known issue:

Has anyone else experienced bad render quality after switching to the latest daily (15/10/2021)?

I updated from daily 06/09/2021 and immediately noticed two interior scenes I was working on became very very splotchy (light leaks and dark spots in corners). I didn't have time to fuck around as I had deadlines (I know it's not advised to be updating mid-project but Corona is usually so damn stable that it's often tempting) so I reverted back to Sept 06 version and all is fine again.

I'm asking as I'd like to upgrade again (decals has me hooked already) but don't want to mess around again with poor quality. Is this a known issue somehow or has anyone else reported such findings?

Thanks.
Hi,

The light leaks and splotches should have been fixed in the build from 15/10/2021. Maybe you will need to regenerate any secondary GI caches.

If you are still experiencing issues please let me know, and if possible submit a scene so we can investigate.

Rowan

Ah! Great to hear. My bad, I actually installed daily Oct 12, not 15 as I said. So should be all good.

Thanks mate.

Quick test with the new Caustics include/exclude: These are all the Caustics element:



Great progress! But some thoughts and issues:

As you can see the caustics are significantly reduced on all objects not in the "include" list (the pool geometry/water etc.), but they're actually still receiving caustics, if you look at the exposure-cranked versions on the right. I think this might be because they are still appearing on reflective objects? So in other words all those other objects that are excluded might not be DIRECTLY receiving caustics but they are still indirectly reflecting them maybe. I think this is not ideal as really the point is to exclude them totally as a visual control.

Also since this is working through include/exclude list it doesn't work at all through XREFs which is a productivity/management killer. Ideally this would work through GBuffer ID and Layer system.

Rendertimes were pretty much identical with/without exclusions (which is expected I guess, but not ideal).

Hi Alex

Perhaps this is similar to what I raised a while back.  I noticed Caustics we still calculated even when turned off - perhaps the same thing/similar to what you're seeing here?  Here's the thread with responses from devs https://forum.corona-renderer.com/index.php?topic=31655.msg178961#msg178961

I think it could be that, yeh. Although I think with an exclude you'd definitely expect and need it to act the way you would expect, i.e. be truly black/null. Hopefully the devs can find a solution, even a hacky one :)

Did anybody notice unusual freezing when rendering is on and you try to interact with VFB? I'm using Oct 12 build and i start to get those freezes very often, somthing that almost never happened before. At the moment i don't have time to roll back to v7 and see if the issue would be gone, but i thought i will ask on the forum if anyone else having similar issues.

This is something that me and someone else already logged here and this is the reason I am not using the 2 last daily builds unfortunately.
I hope it ca be fixed soon.

I'm too hoping for a prompt fix.

Request: Corona decals are not accessible through search 3ds max commands tool, default keyboard shortcut X. Please address it. And i think it would be nice if create decal button would be added to Corona toolbar.

I have 3dmax freezes during interactive rendering. When I switch between cameras or just go to the material editor

Hi Guys,

I haven't noticed this. Can you send over a scene where this is reproduceable?

If the topic has already gone about Caustics, they began to notice empty squares.

Hi Larry3d,

Can you send this scene over to us?

Instructions on how to do so can be found in my signature.
