You can group your Render Setup collections, then export these groups as a .json and re-use the template in a new scene.
Create groups within a layer or a collection by right-clicking and selecting Create Group. Nested groups are supported.
You can isolate select a group, and all of its members (child groups and collections) are also isolate selected as a result.
You can enable and disable groups as you would collections. If you disable a group, its members (child groups and collections) are also disabled as a result.
To export a group, right-click and select Export Selected as you would any collection. You can import this template into any layer, collection, or group.
Groups are included with the template if you export a layer that includes a group, or if you export a Render Setup template via Export All that includes a group.
