7) runway signs in ALS still rendered as terrain and have assigned texture
of rocks/cliffs.

> functionality already) and run a version of the urban shader without the
> relief effect if random buildings are on. That appears to be working fine:

> FredB - is this a modification to the urban effect you can agree with?

> 6) there's still a 'crack' in the sky visible when the skydome shader is
> used. Based on the color of the crack which just shows the color of the
> default sunlight underneath (which the skydome shader can't possibly know),
> I believe this is really a fault line in the geometry and that it can't be
> fixed within the shader code.

> It'd be nice to be able to get rid of some of these eventually - please
> let me know if anyone is working on any of these and I can start picking up
> things from the other end.
