Question is, how to spawn 3d object from UI node , example we have - Canvas UI with Camera and we have Root Node in 3d space with Main Camera to render, so i would like to spawn 3d model from ui node position, and keep 3d model parent in Root or child node of 3d space , is it possible?
how to convert ui node position into 3d space node, confusing.

suppose we have scene , with 2 cameras 3d and 2d.

There is the method in camera, screenToWorld, that will convert the screen pos to world pos(3d space pos).
