I made custom 3dos for both a door and an elevator platform for my Doom 2 conversion level. My problem is that when i insert them in the level, the door freezes the game when you shoot at it, and the platform some of the surfaces on it can't be stood on, and they are all flagged floor. Also, for both of them, so of the textures keep disappearing. Also, do you know if there's any way i can put a working switch on a 3do? I doubt there is, but I know many people on these forums have more experiance than me.

What parent template did you use for them? Are there any unusual cogs attached to the door? Also, make sure they are entirely in one sector.

A working switch on a 3do? Nope. If you activated anywhere on the 3do (not just on the switch part) it would trigger the cog.

Well, for your first problem I would check your consistency while editing the 3do. It sounds like you have some problems with surfaces. As for creating a switch with a 3do, you can do that with a cog. For help on that visit the cog section.
