Addon for batch rendering of collections.
If you need to render a lot of objects of the same type (collections), then this addon is made specifically for this.
Create a collection such as Render.
Make links to the collections you want to render. Transfer them while holding down the Ctrl button to the created Render collection.
Indicate in the addon the Render collection containing other collections for rendering.
Specify the path for the finished image and click Render All.
Rendered images will appear in the folder you specify.
Note. Collections in the collection for rendering need to be dragged with Ctrl pressed - then links to them are created. Everything that is included outside the Render collection will be included on all renders.
