Can I combine 2d and 3d?

Ronnypac

have a game idea in which 2d and 3d elements (scenes) should appear, 2d as a GUI and map 3d for certain game elements, I just wonder whether this can be combined, the tutorials I have seen so far only made 2d or 3d.

Yes, this is no problem. For GUI and HUD elements, usually you will use a CanvasLayer, which will draw above the 3D screen and you can use this for health bars and ammo and stuff that doesn't move. You can also combine 2D and 3D in other ways using viewports, for example if your game has a 3D smartphone in it and you want to control a 2D interface on the phone, you can do that too (or 3D in 3D, like security camera on a TV, etc.).

Thanks for the quick reply, this was not actually mentioned in any tutorial and should be included in the documentation.

That's a good point. Looking at the documentation now it is not obvious how it works. However, you don't really have to do anything special in the case of 2D over 3D. You can basically just add the nodes and it will work.
