Title: Corona License is always occupied despite of used Render Engine
Post by: brr on 2022-11-09, 11:34:44

Dear Corona Renderer team,

I have strange license distribution behavior. Using Corona and Vray and regardless of Render Engine, Corona license remain busy.

Tested with:
1. 3ds max 2022.3.6 / Corona 9 / Vray Next 4.3
- starting new scene with scanline renderer as default - everything is fine
- switching render engine to vray next - one vray next license is in use
- switching render engine to corona - one corona license is in use , no vray license is busy
- switching back to vray or anything else - one corona license is still in use

2. 3ds max 2023.1 / Corona 9 / Vray 6.HF3
same steps and same situation :(

In general: you need to switch the render engine to Corona only one time and corona license will be used forever. Only if you close 3ds max, then it restores again.

You can see some images in the attachments.
PLZ Halp !

Best regards

Hi, this is currently the expected behavior. There are some differences between how Corona and V-Ray engage and release licenses. We would like to improve some of these behaviors in the near future, and make them similar across different software as this may be confusing.

Sorry for this question, it is probably obvious to you, but can you please explain why the current behavior is problematic to you? In what exact case would you prefer the V-Ray behavior?
Once we know that, perhaps we can come up with some solutions/workarounds for your specific use case.

Hello Maru,

sorry for delayed reply.

In my case, the company where I'm working in, bought X Corona licenses for larger amount of users. Most of the users have different tasks and using Corona to shading/rendering up to time. Sometimes some users need only to open the scene to look into details and export the lines to do some technical drawings, or just for modelling (without shading). If corona renderer is set by default, the license gets active when you start 3ds max and in some cases we reach license limit. Same time, other users who really need to render cant do this, because somebody needs to reset default renderer and close 3ds max.

It will be really great to have some tolerance while checking the license:
corona is renderer by default ? ⇾ no license needed
want to render or shade ? ⇾ check license

Hope you understand this situation.

Best regards

Hi,

We have this reported and will be changing the behaviour in v10. Standby for the daily builds :)
