Chaos Corona for 3ds Max => [Max] Bug Reporting => Topic started by: Oltiabga on 2025-06-24, 15:58:27

Hi everyone,
I’ve encountered a recurring issue when adjusting values in the Post or LightMix tabs inside Corona VFB. Sometimes, I try to enter values manually (either via the top number row or the numeric keypad), and it simply doesn’t register certain numbers—notably the digits 2 and 8.
It doesn’t happen consistently, but when it does, the only workaround is to click away or reopen the VFB.
The issue has occurred on three completely different PCs, with different hardware and fresh Corona + 3ds Max installations.
I'm using the latest versions of Corona Renderer (13.0) and 3ds Max (2024 and 2026.1).
Because of this consistency across systems, I believe it’s likely a Corona UI-level bug and not related to my hardware, input device, or keyboard.
Has anyone else experienced this?
Would love to hear if there’s a known fix or if the dev team is aware of it.

I don't think this is anything we are aware of. I am not aware of any other forum reports or support tickets. If it was a global issue, I am sure we would be getting lots of user reports.
Personally, never happened to me either.

Hi,
I have experienced this multiple times already, happening very rarely. As you mentioned, the workaround is either clicking away from VFB, either reopening it.
So far I have come to the realization that this is 3ds Max hotkeys still taking effect in VFB - even numbers on numpad are shortcuts for 3ds Max. I believe I have experienced this same thing in a non-Corona related UI (I think it was PhysicalMtl) too.
I do think this mostly happened after walk mode was used - does this ring a bell for you?

I have also experienced this several times over many years. Seems to be a window focus issue as you say.
