Hello. I want to do a transparent location floorplan for my interactive VR app. I am guessing doing a top camera that has a transparent plane with the floorplan in a Alpha channel. Then use this camera as a render to texture and apply the texture on the main camera via a GUI texture. Is this ok?
I tried to do the procedure and sucesfully rendered the top camera to a texture and applied it to a GUI texture, but I cannot make the background of the top camera be transparent. I tried all of the clear flags on the location cmaera, but never could make the rendered texture RGBA and not only RGB, thus getting a rectangle of the camera’s Brackground Color and not a nice overlay. Any ideas?
