so i finally got my costume architecture in to the creation kit, i didn't import such a complex mesh just a small box to test it all out.
so now i'm a little confused, I place my box in the game world but my character just runs straight through it... how to i make him collide with my object? i heard some people mention that i need collisions, but how do i do that?
thank you

Read through this http://www.darkcreations.org/forums/topic/1920-exporting-static-meshes-for-skyrim-from-blender/, it has good info on collision.

Yes, chunkmerge works fine for custom meshes ...

for very simple objects you can use the CKs collision primtives (but way more work)

Aye, thanks folks
