I'm going to be making a tut on easy windows for differnt or oddly shaped objects.
I just figured this one out. I'll be posting my findings soon.
Anyways till then I suggest you look at this post for adding windows into hulls.
my tut is going to be really easy
I mean you could put these windows any where.
ooh if you want to make a hole in an surface click the surface you want, go into surface mode. Go up top to where it says objects, surface and vertices click on the surface tool. A list of things should pop up as bevel, indent make hole, etc.
click on the make hole.
I hope this helps
