Custom Doors Creation

Hi there!

I created custom door by Blender.
It works great. I animated the door too.

But… I have no ideia how to add DWK meshes. And how they work.

Maybe is here anybody who can show me your Blender-Door-Project?
A good working example will be better then 1,000 words…

I use Blender 2.78.

PS: My blender project now looks like that:
PSS: I’ll add die, dead, ect. animations later of course ^_^.

PSSS: I tryed to imports CODI’s bloodwar doors, but there is an error…
