I actually hoped it was working locally, and not an image that's uploaded each time to chaos, and then enhanced on chaos servers.

(I could actually imagine that this will become a credit/money thing one day ?)

Thanks!

probably a 3ds question, but where do you select the "looks" (i mean the one you've set up with the red creative lut) with ocio ?

[Max] I need help! / DRSERVER soft terminate

« on: 2024-10-29, 11:47:30 »

Hello,

on two fresh installed renderslaves running win10, corona12 hf1, 3dsmax2025, DRserver somehow closes after some renderings automatically, without any specific reason.

in the log is says : DR slave received command SOFT_TERMINATED

Scene was originally modeled in 2024, then opened in 2025.

Render with DR works fine, but at the end, DRserver is closed on render slaves (even if 3dsmax.exe remains running in background)

Any ideas ?

[Max] Resolved Bugs / Conora light reflection in shadowcatcher

« on: 2024-09-21, 17:19:51 »

Hello,

is it possible to have reflection of a corona light in the shadowcatcher material (where reflection is enabled) ?

I only get the object reflection, and not the light.

edit : Ignore, i forgot to tick the "shadow catcher illuminator" in the coronalight property

edit2 : well, if a coronalight is behind a glass material, it is not visible in the shadowcatcher reflection, so that is problematic (imagine a building at night, with lights inside the appartments, not reflecting on a river that's on a foreground shadowcatcher)

Thanks

[Max] General Discussion / Multi/sub-object mtl in Rayswitch material mtl ?

« on: 2024-09-12, 13:19:45 »

Hello,

is there any way to place a multi/sub-object in a Rayswitch material ?

I have a multi/sub-object material with 500 sub materials from in imported fbx (google 3d mesh imported). So quite impossible to do it manually one by one.

I need this object be visible only in reflection, no refraction, no gi.

Is there any other way to achieve this?

Best,

same feeling here (corona12 hf1, max2024 or max2025, nvidia rtx4090)... material UI is sooooo slow, even on a complete new empty scene

baked the 128px didn't change anything

[Max] Resolved Bugs / 3dsmax2025 Corona12 small icons ?

« on: 2024-07-24, 10:32:00 »

Hello,

on a complete fresh install of 3dsmax2025 with corona12, when you set up the icons size to small in the max preferences, there are icons of corona12 missing : create chaos scatter, open scatter lister, scatter helpdesk.

the buttons are still working, but no icon is visible

they appear when they are in normal size.

All the other icons are ok and visible.

[Max] Bug Reporting / Re: Corona 12 - Path of LUT's

« on: 2024-07-09, 11:03:20 »

Hello Chaos,

has this been identified and logged ?

It happens also with Cosmos/"Corona Materials" textures btw that are saved on the same network folder!!! So this is quite a huge problem IMHO...

For normal material textures, it seems to be ok though.

Thanks

[Max] Resolved Bugs / Corona 12- denoiser turned off

« on: 2024-07-06, 12:15:39 »

Hello,

it seems that on corona12, the new vfb somehow turns off the denoiser tick in the VFB automatically, eventhough it is enabled in the rendering settings.

Resulting in needing to re-enable it before launching a new rendering.

[Max] Bug Reporting / Corona 12 - Path of LUT's

« on: 2024-07-06, 08:42:36 »

Hello,

it seems that in Corona12, the path of LUT files placed in the VFB, that are saved on a mapped shared drive (ex: m:\assets\luts), are actually saved with the ip adress (\\192.168.1.0\assets\luts)

when working on other sites, where NAS servers are synced between the different sites, corona12 is looking for the ip adress, instead of the mapped shared location. This results in error messages when opening the .max file.

It used to work fine in corona11.
