Question about different texture types

[cruizer]

I know when creating a brushed with visible textures, it's bad to overlap them. But what about brushed with invisible textures, such as playerclip and nodraw?
Will overlapping a playerclip texture with a visible texture cause slow rendering in game, as if you overlayed visible textures?

Also, when ysing playerclup at an angle over stairs, do i need to make that a func_detail as well? Or is it fine left as a world model?

Overlapping clip brushes or trigger brushes with with texture faces wont affect anything. I dont know about nodraw through. Maybe you should try it and see what happens.

You don't need to make playerclips func_details, becuase they're only used in the physics collision step in vbsp. I also noticed if you make playerclips funcdetails you can't hide them using the clip visgroup...

playerclip isn't rendered so no, i wouldn't of thought it would have any impact on either of the situations you posted.
