Corona 12 Update 1

[romullus]

Weird mouse lag here as well, sometimes it just moves where it wants and I can`t do anything. In IR, in SME, over a more complex object, so all of what has been said above. Everything worked fine until this update.
And the biggest problem is that if I install Corona 12 HF1 the scene won`t start, 3dsmax ( 2024, updated) will crash while loading the scene. And it did that even when the scene was under 9 mil poly which is pretty light for how I work :d
This time updating was such a big mistake

Try to install Update 1 again, open the scene, delete all Corona cameras, save the file and try to open in HF1. See if that helps. On the other hand, as it was said many times before - if you update in the middle of the project, always do backups!

Thanks! I did remove all the cameras ( saw this in another post) and it didn`t work. It did give me a different type of error but the scene would still not open.
I updated before starting this project, just a week ago...so even 'smarter'...nothing to backup :)))

Mouse lags when COSMOS browser is OPENED.

Is there any news on fixes to this issue? Heading into a massive project at work this month with big scenes. Just want this issue fixed so it doesn't bog down our productivity.

After recieving an official mail from Chaos to take action in term of Licensing (the server certificate will expire on January28, 2025) I followed their instructions to update the chaos products to their latest versions.

After that action i am facing very laggy and bad workflow performance, specially: viewport navigation, mouse behaviour, slate material editor, decals not working consistantly, working with cosmos and general responsiveness issues when interactive rendering is active.

Info:
-3dsMax 2025, latest update on a fresh installation
-Corona 12 Update 1, latest update on a fresh installation
-new fresh simple and basic scene
-no additional installed plugins

Question:
Any ideas or solution how to deal with these issues?

Thanks, Frank

Hi Frank - You may have more luck with Corona 12 HF 1 rather than 'Update 1.' HF 1 was available to download again last I checked.  I rolled back from Update 1 to HF 1 and most of the major lag related bugs were gone.  Word on the street is that Update 1 will get an fix this month.

Also in my experience Max 2025 uses quite a bit more VRam even with empty scenes (probably not even Corona related) so I rolled back to 2024.

Hope that helps, others may have more.

Hi,

There were reproduced lags and responsiveness drops, which have already been tfixed internally.
Be sure to try the next daily build which will be out soon, which should have all of these slowdowns addressed.

The Cosmos being open resulting to lag is/was new, so if it continues to happen with the upcoming daily build, please record a video with some repro steps and send over.

Hey Aram,

if you already know about the issues on Update1, please let your users know about it.
In this case i (and other users as well) wasted a lot of time to fix it and i was looking for installation issues and hardware issues on my end.

Hi,

It was actually users, and only some of them, that let us know about UI lags. Internally, we did not see consistent responsiveness drops, which led us to think that this may be hardware specific. The whole discussion has been here in the forums, which was the only place to give and receive info on this topic. Can you please let us know what hardware specs you have?

How soon can we see a hotfix to 12.1? I'm on 12 hotfix 1 and it looks like I'm being forced to update because of licensing. Will 12 hotfix 1 still work on the 28th?

Oh, I see there is now a hot fix to the update!

[TomG]

Yes, Corona 12 Update 1 is the first version to feature the new licensing, any older version (including Corona 12) will stop working on Jan 28th. Yes, there is now a Hotfix for Corona 12 Update 1 :) Also, you can update the licensing server manually if you don't want to update your Corona version, there is a detailed guide at https://support.chaos.com/hc/en-us/articles/30185867975185-How-to-update-your-Chaos-License-Server-Version . Hope this helps!

[JG_monomiru]

is this for real? i mean corona 12.update 1 just came out and introduced a lot of pain for many - and you stating here that everything before corona 12u1 will stopp working after 28th of January?

will there be an official information to every license-holder? I mean Tom you're kind of official - but that doesn't mean someone need to accidental read this info in this forum.

what if i have a running project and don't want to change corona versions inbetween?

or are we talking just about the license-server?

[TomG]

We're just talking the license server. The easiest and recommended way to update that is to update to 12 Update 1 (Hotfix 1), but if you don't want to change Corona version you can just manually update the license server as mentioned in my last post here.

Info was posted here in the News on the 5th December last year (always worth following as it has all our releases in it) at https://forum.corona-renderer.com/index.php?topic=44052.0, there's a big banner on the website, there's a banner in Cosmos, emails were sent out (and there will be a reminder email too), and I posted a reminder note in the Daily Builds discussion forums for both Max and C4D, so we haven't just relied on folks reading the News on the forum. The link here to the original News posting has the full details, including the link to the page describing how to manually update the licenser server (https://support.chaos.com/hc/en-us/articles/30185867975185-How-to-update-your-Chaos-License-Server-Version if you want to go straight there).

[JG_monomiru]

Well regarding the E-mail notification in December - no such email under the mail i got my corona license registered.
