[HELP!] GameObject disppears when using NOVA UI

[twilightsight]

After building up a UI by Nova, it worked well. But When I created a gameobject like cube or sphere, the gameobject disappeared when I ran the scene. Instead, I changed it to Canvas, it worked well. I tried to bind script like canvas renderer or UIBlock to the cube, it all failed. And I checked the camera and gameobject and made sure that it was placed at a positive position. I plan to use this UI toolkit to try some ideas.

My Unity version is 2022.x, and nova version is a free trial version. Any suggestion is OK. Thanks very much.

Maybe I get the answer. I didnot find the renderer related tips before. It needs a 3D block and set a proper value in the parameter of render queue.
