Hi, everyone. I'm new to Godot and I'm trying to put the UI in 3D environment. I want to render UI(the one in 2D scene) i got it from Dialogue Node into the 3D env.

I have created a OpenXRCompositonalLayer(where I want the dialogue to be displayed) and a subviewportcontainer to put the UI into the layer. However, when I looked at the main scene, it seems like its being rendered(2nd screenshot) but when I played the scene in headset, its just completely gray. I have tried to change the options in Render Target, Viewport from the inspector and nothing seems to work. I have also noticed that the dialogue was showing in the subviewport but its showing nothing on the 2D scene(1st screenshot). Any feedback would be appreciated! Thank you.

Is there an specific reason for using a SubViewport?
A CanvasLayer should work.

If im not mistaken, OpenXRCompositionLayer does require me to select Subviewport in order to display it in 3D env.
I tried to change it to CanvasLayer, the UI was showing in 2D but not in the VR game itself

#

I tried to use CanvasLayer only in main scene but nothing shows up

its fine, ill try to look for different solutions. Thank you once again!

Another noob question, if I were to do that in normal 3D scene, is adding UI into canvaslayer is enough or i still need to add camera or other things for it to be shown in 3D scene?
