Delaying the first player spawn

[Ian_Suffix]

Hello, Villun mappers!

I have a question that may have no answer: is it possible to delay the first spawn of a single team in TF2? I find it necessary to delay the first spawn of the RED team, so as not to reveal an embarrassing problem with the changing environment that reveals itself only in the first second of gameplay-- that is, the first second of the Waiting For Players and Setup time.

It occurs to me that if necessary, I could make a fake 'waiting' environment and then teleport them to the real one, but this would require knowledge of cameras or 3D skyboxes or whatever. If you can't delay somebody's spawn time at the beginning, could somebody explain how to use 3D skyboxes?
