Billboard outside of camera frustum
Hi,
Does anyone know how to create a backdrop as a billboard that is visible outside camera frustum?
I want to create a city skyline backdrop in a scene where the camera far clipping plane is 100m and the level is about 500x500m, so I am guessing that I need to place a large billboard at a distance of about 1000m from the scene centre, but this will mean that it will always fall outside the camera frustum?
Thanks!
2 solutions : - Use a skybox (that's what it is intended to) - Use a 2 camera setup : one that renders first and only displays the backdrop (with corresponding clipping planes), then the second camera that displays the rest, but with the clear flags set to "depth only" (so depth is reset, but the color rendered by the previous camera is kept)
The two camera solution seems like a suitable solution for me I think, thanks. I will be looking into ways of using two cameras simultaneously.
