ok, sorry. I just tried with the trial version, created simple hollowed block and inserted some mdl models. Every world building process cancels with E701 error. I even cannot create a simple room.

When I remove static meshes then it works but lighting is wrong in the corners. UV-map of light-map leaks the light.

So even without static meshes it looks worth than A6.

I am looking forward to Spritit's shots. I have to give up. It simply does not compile at all.
