I'm with Curt. Coming up with a single Z range for mountains and gauges isn't likely to work well. A better idea would be to investigate glDepthRange() to isolate the two regimes (this trades ~1 bit in depth buffer precision and allows you two or more completely separated clip plane sets). Or just turn the depth buffer off for the cockpit and sort the geometry; for most cockpit layouts, this should be pretty feasible. It won't work if the cockpit has moving parts (yokes or whatnot) that obscure other pieces. Or just eat the cost and clear the depth buffer between the scenery and aircraft/cockpit. On modern hardware, it's actually not that expensive. Andy -- Andrew J.
