URP Camera stack with multiple renderers : nothing showing

Hello !

I am working on a 2D project that also implies TCG mechanics. The cards are the only 3D Objects.

I use URP with 2 cameras, a base camera for all the 2D objects (we'll call it 2D Camera), and an overlay camera to render the cards at the bottom of the screen (we'll call it 3D Camera).

Since I want to use 2D lights, I created an URP 2D Renderer, that I set at index 0 and as default in the Render Pipeline. Since I also want to use emission and normal maps for the cards, I needed to create a normal URP Renderer that I set at index 1 in the Render Pipeline.

The cards are on their own layer, that is not renderered by the 2D Camera. The 3D Camera only renders the card.

The problem is that the cards are just not being rendered, even though I set the 2D Renderer as the renderer in the 2D Camera inspector, and I set the URP Renderer as the renderer in the 3D Camera inspector.

Am I missing something ?

Thank you for your answers, Best regards
