Hi,

I've made some new meshes for my house and I got collision working but can anybody tell why I can't see any impacts or similar.
For example when I use a fireball spell I can see that it explodes on the correct position but no impact texture appears.
And if I shoot an arrow it just disappears when it hits the mesh.

Any idea what I have to do?

Use NifSkope to compare all flags on collision related nodes between your custom mesh and a vanilla building mesh?

Oh, it might also be related to the material type of the nodes in NifSkope.
