Question

Hello!

I am curently working on a project where I have put together several 2D scenes, Main menu, intro cinematic, then multiples images linked together with buttons. Everything works so far.
My problem arises when I want to create a 3D scene. No problems in the viewport (player and world scenes) but as soon as I want to try the scene, the render is full black.
I have set the player scene with a Charabody3D/CollisionShape3D/Camera3D and the world scene with a 3DNode/WorldEnvironment (with proceduralSkyMaterial)/DirectionalLight3D/instanced player scene.
If I create those two same scenes in a new project it works however :confused:

If any of you have an idea about this, I would be very happy :stuck_out_tongue:

Thank you.

Ps: I tried googling it but no luck.

Can you share your scene tree? Is your camera inside of a mesh?

There are no meshes in the scene for now.
