[Max] Bug Reporting / CoronaSky Volume Effect problem in Corona 13

« on: 2025-06-26, 20:47:48 »

There is a big problem with Volume Effect in CoronaSky in Corona 13 (in Corona 12.1 it is ok). In Corona 11 we can turn on Volume Effect and use it with every environment map but in Corona 13 we can't do it. It is a big problem to migrate all previous scenes to Corona 13 because of this. Is there any way to turn this behavior on in Corona 13?

I've attached scene with this problem. If this scene opened in Corona 11 it will have Volume effect renderable, but in Corona 13 it is not renderable.

[Max] Bug Reporting / CoronaPattern + CoronaLight Material = Crash

« on: 2025-06-22, 08:33:24 »

From version 12 there are no way to use CoronaLightMaterial with CoronaPattern. Emit light option unsupported, as manual says, and leads to black appearance, that's ok (not). But if this checkbox is unchecked it crashes 3ds max at sec GI stage in Corona 12 and above.

[Max] Resolved Bugs / Low CPU usage with passes

« on: 2022-06-20, 08:07:20 »

Every pass CPU going to 0% usage and this leads to overall usage nearly 50% of CPU power. I investigate that with adaptivity off this gaps going to shrink a bit but always there.
Is there any ways to avoid this behavior?

[Max] Resolved Bugs / Broken animation key set in new Corona Tone Mapping

« on: 2022-04-19, 14:12:53 »

Key adding by Shift+Left click not working in new (broken with old scenes!!!) Corona Tone Mapping. More of this it is strange behavior of resetting to default by right click not only over arrows near numeric field but over numeric field itself.
And on top of this there are no color brackets (showing existing animation key) near arrows too.

There is a bug in Corona 8 with "Cast shadows" parameter in object properties. Unchecking it with map in diffuse can't switch off shadows completely.

Hardware / CPUs with 64+ cores

« on: 2016-07-04, 18:15:52 »

Is anyone knows how Corona utilises more than 64 cores as there is more than one Processor Group in Windows. I remember than VRay had a problem with this. I want to buy 18-core dual CPU Xeon want to use all of them in Corona. Is there any issues with it?

[Max] Resolved Bugs / Reflection bug - ugly distortion

« on: 2015-11-19, 09:22:00 »

Found strange bug with reflection. Near 0 degrees angle there is an ugly distortion in reflection present.

Look at video.

There are only plane with "mirror" reflection and sphere with light material. As the camera going down to nearly lay on the plane reflection distorts.

Sample file attached.

[Max] Resolved Bugs / 1.3 Proxy mapping error

« on: 2015-11-10, 07:00:32 »

I faced strange proxy behavior in 1.3

Some proxies (.cbin) have no mapping coordinates in 1.3. I rolled back to 1.2 and the same proxies are good with mapping coordinates. I hope no one will "help" me with advice to convert all my proxies in all projects to newer format!

[Max] Resolved Bugs / Long scene parsing 1.3

« on: 2015-11-05, 07:12:35 »

In previous versions (pre 1.3) of Corona it was "normal" to expect long (~4 min) scene parsing with backburner network rendering. But in 1.3 it grows up to impossible 6-8 minutes. Plus 3dsmax.exe process seems to be freezed as it can't be closed even by task manager for some time (at least in DR mode).

On pictures you can see scene rendered with 1 minute time limit. Scene parsing takes up to 8 minutes at random frames and servers. No DR used.
