Project camera view on ground plane

Hi all! I’m trying to project the current camera view to the ground plane. I render the scene to a renderTarget and then apply the renderTarget-texture to the plane-material. This doesn’t work that well, since the texture isn’t correctly mapped to the plane. Does anyone know of any docs, or threads, with similar issues?

Goal implementation

Here’s a demo example of using render target.

Hope this helps
