[Max] General Discussion / Re: Corona 12 a lot slower on old scenes

« on: 2024-08-26, 09:17:29 »

Same here—I just made a post about it. There’s definitely something off with version 12. It’s noticeably slower when we test it across our machines. As a school, we have several computer labs with completely different setups, so it's not a specific hardware issue. Scenes that ran quickly in version 11 are now sluggish, even when merged into empty scenes. This seems like a software issue that needs to be addressed ASAP.

[Max] Bug Reporting / Corona 12 feels sluggish?

« on: 2024-08-26, 09:09:47 »

Is anyone else noticing that the latest version of Corona 12 feels slower compared to previous versions? I've been using the same test scenes for years, running them on different machines with consistent software setups but varying hardware, and I've observed a significant drop in speed. Even my students have been complaining that it feels sluggish. Is anyone else experiencing this? I'm running Corona 12 with 3ds Max 2025 on Windows 11

[Max] General Discussion / Photographic exposure in camera not working well!?!

« on: 2022-11-04, 10:58:28 »

Since Corona changed the setting where you chose to use Photographic exposure in camera to the Frame buffer itäs been acing strange. Has anyone else been having problems?

Allways had good resules with real world camera values, but since the change I often run into issues where I need to cranck it up to stupid values like ISO 6000, F-stop 2, shutter 50, and it¨s still rather dark?? And no it¨s not any rookies mistakes like bad lighting.

Yes it still happens. When it first happend I was sure it was an issue with google drive trying to backup somthing and that made Corona freak out so I told everyone when they doing overnight renders to place project on desktop and just render from there. Still happend.
Could it have anything to do with "relative to the project folder"

I have some 30+ students that use Corona render and we´ve been teaching and useing corona for many years. Suddenly my students started complaining that they got this error and ther render got abortet.

"Render had to be aborted because a bitmap on disk changed and is being reloaded. Continuing the render could cause crash or undefined behavior"

I found this info on the support page that "solves" the problem but I still don´t understand why everyone suddenly was getting this issue? Is it a corona 8 problem? Only other this that has changed is they use google drive to store files but in ofline mode.

We´ve updated drivers, reinstalled, Killed the ENU map. Smae thing on different specs of laptops.

[Max] I need help! / Converting from physical material TO corona material?

« on: 2020-10-14, 13:51:13 »

If you have a scene that has been converted to physical materials can they be converted back to corona? I know corona can render physical but was hoping not to need to work with multiple material types.

[Max] I need help! / Strange reflections during render that dissapear over time???

« on: 2020-10-14, 13:49:12 »

I've seen renders that get strange effects that over time disappear. Both massive colored reflections that over time clean up and aren't visible in the end render and strange effects where you see massive pixels like if the bitmaps where super low rez.
I'm thinking that the scene might have non-corona lights? or some new progressive setting? The image looks right after rendering for a long time but it's irritating not knowing how the end result will be.
