Hello!

In Type Script headers BABYLON 4.2. **Engine.activeRenderLoops** not present. It depricated accessor?

If ‘yes’ could you explain how correct get render loops list for engine in further?

Thank you!

Should be there! We haven’t removed it. It is a part of the engine itself and not the engine class, if that helps:

Actually, `engine.activeRenderLoops` is new in 5.0.

In 4.2 you didn’t have access to this list: there’s a `_activeRenderLoops` property but it is private. In 5.0, we made an accessor for this property.
