Title: "3D Sky actor" making problems..
Post by: FogGobbler on February 04, 2009, 02:32:32 PM

Hi!

I´m using a "3D sky actor" for my ..ehm.. sky.

I just use a cylinder that slowly rotates round the scene. At the beginning everything is fine:

But after a while the sky vanishes, leaving behind a "black hole" ;-)) . After a while it turns up again...

I´ve turned on drawbackfaces and fiddled with the normals, but nothing works :-(

Are the texture dimensions powers of 2?

Does the scene cam have to inside the rotating cylinder or does it have to be outside?
Another very strange thing is that the rotation speed alters. It starts of slowly and speeds up  ::slug
Perhaps it´s a positioning problem, could that be the problem..

Very puzzled Oli
