Something’s wrong with colour picker in December 13 build, the swatches are not keeping their colour and overall are acting weird. Also there’s that annoying half-checkered thing, but that issue started to happen few weeks earlier, not sure if it’s Corona’s fault or bug in 3ds Max 2024.2 update.
Thanks for the report! We are aware of both things and investigating.
Fun fact: the “transparency” part of the color swatch is expected in some cases. For example, if you create an Autodesk Physical Material and change its diffuse color - you will see that the Corona Color Picker allows setting alpha there. But it should not appear in all color swatches. The fix for this is usually collapsing and expanding the material editor rollout again. So it looks like a UI glitch.

There is also picker always sampling black when using multiple monitors - (Internal ID=886677936)
Does anybody else experience crashes when using VFB history in Corona 11 and 12? Crashes happens without 3ds max error message and does not generate minidump. Could be scene specific, since it happened to me several times when working with certain scene.
I am not aware of this. What exactly do those crashes look like? Is it 3ds Max disappearing completely so that you don’t even have time to capture a minidump?
It happens when i want to do VFB history AB comparison - try to grab and move divider, but Max freezes for a few seconds and then disappears without a trace. Doesn’t happen always, or even too often, but i had few such occasions in V11 which i don’t recall to be happening in older versions at all. I don’t do any rendering lately, but if it happens next time, i’ll try to figure out if it’s reproducible and if i can provide you with the scene to investigate.
I did not manage to crash it, even in a non-teapot scene 
, when rendering in various resolutions, IR and production render. If you figure out reproduction steps, please let us know.
Don’t use such scenes, you may encounter bugs ;]
Good Luck
Found another colour picker related bug in Dec 13 build - IR is constantly refreshing when one is adjusting tint colour in Corona colour correct texmap.
Thanks, confirmed also in 11 release.

I don’t get that error, but i noticed that even disabling out of core, does not completely prevents Corona from temporarily writing to the disk some OOC related stuff, which is quite upsetting TBH.
TBH, This out of core has been nothing but a headache since day one of its arrival.
I don’t use it. I don’t want to use it. But it still causes crashes, often, and now this annoyingness too.
We do use it, Corona is NOT good managing the ram, we have 128gb in all systems and we Need to use it on various scenes in order to render, but the pulze plugin can interfere with the paths.
Hey,
I bet this is really frustrating. I have tried numerous times to reproduce this here, and I have failed every time. Can you provide a list of every plugin you are using and if you are using any render managers?
Cheers,

Yes, I am using Pulze SM. (Ad RM).
Apart from that it’s just Phoenix, I think?
I think one issue is that I cloned my PC… then on the clone changed the user and PC names. It’s searching on my old user folder.
However, this only started happening when I upgraded to C12. It worked fine for 1-2 months on C11.
I’ve been playing around with the displacement lister today for the first time.
First thing, it seems quite buggy. If I rename one of the materials that has displacement while the lister is open, it seems to crash. Also if I open the lister, close it, then rename a material and re-open the lister. This is happening in a very heavy file though, so might be hard to replicate.
Second thing; it’s a bit strange that displacement has an on/off toggle in the lister, but not in the material settings? Is there not a way to turn off a displacement on a material any other way than the lister? Edit: Ah, I see it’s toggle is in the maps list at the bottom of the material properties. Maybe this should also be in the displacement settings area of the material?
Apologies, I think I might have possibly led you on the wrong track!
Although this did start with C12 installation, it is also possible that it’s Pulze SM causing the out-of-core file location to reset every time I load a Pulze scene. I think perhaps the settings override might have this saved, hence it defaults back to an invalid drive every time.
Worth checking out anyway.
hey guys is there something wrong with corona lately? there are certain scenes where the suns position seems to change everytime i re-open the scene? currently on corona 11
This and some other issues has been fixed in Corona 11 HF1: https://forum.corona-renderer.com/ Corona 11 (Hotfix 1) released for 3ds Max
