There are many possible uses for this addon - it all depends on your imagination. In general, the idea is that in a scene with multiple cameras, once rendering from one camera is finished, rendering from the next one begins. This applies to both image and animation rendering. Since rendering is usually a lengthy process, the addon also includes the option to preview its functionality in advance.
This release introduces new workflow possibilities outside of sequential rendering as well. Now it is more general-purpose.
Introduced select camera feature.
It allows to make selected camera scene's active.


This feature allows to set different settings related to render for each camera in the scene separately.

On a screenshot above you can see flags that can be captured per camera. At the moment they are unchanged from the Individual Camera Properties addon, so existing users should not be confused, but in the future they may be extended to support more features.
More end-to-end tests
Both new features are covered by tests, so they should be ready for production use. Added mixin tests, which are checking if all existing functionality works well together.
Both new features are already implemented in other addons, but they both are incompatible with Multiple Camera Render. As you can see from issue report, almost 14 hours of render time was ruined, which is inappropriate.
However, was decided to implement similar features in compatible way as far as it opens more workflow possibilities. No code was "stolen", Multiple Camera Render have different implementation of both features:
This extension requests the following permission:
Writing execution log files inside extension directory
That's good, from my experience, alternative solutions is always nice to have. Thank you!
Works great.
Seems to lock the UI. I have rendering set to keep UI, and normally switch to my rendering workspace if I want to see progress, but with this I can't do that unless I switch to the rendering workspace tab first. If possible, would be nice if it didn't completely lock the UI.
Originally it was done for optimization purposes (to prevent user from deleting cameras during rendering, so camera queue can be evaluated only once). The addon itself is opensource, so you can easily tweak its behavior. If you not familiar with coding, AI tools can do it for you ;)
I'll consider this for next version, Thank you!
Literally changed my animation and rendering pipline, this is so helpful and It helps me save so much time when working on scenes where I have multiple angles of a model
It's nice to hear, the addon was created for similar tasks btw. Thank you!
Good add-on... I have written simpler ver just render Viewport and Cycles, Active select camera.
