[Tar-Palantir]

I've created a model, but when it goes into FS2, there's nasty sawtoothed like lines where one polygon joins to another, as in:

My question is why and is it related to the strange red polygons shown on the bottom image. The body was one object, the missile pods are a second object which has been intersected(?) with the body. I've then stuck cube around it and intersected(?) that. For the intersections I used the buttons with two spheres overlapping each other in TrueSpace.

The vertical sticky up tail was done in the same way, but that does not show any of the problems the rest does. Can any one help?

i haven't understood exactly what you did, btw this effect is caused by polygon intersection

Well basically I created the missile pod shape, but half of it went though the main body - so it would not be visible. I then used whatever tool* it was to remove the parts which were inside the main body, therefore they should be no polygons passing though one another.

*The symbol is two spheres, one green and one red, joined. One is lighter in colour than the other.

When you say 'effect is caused by polygon intersection' do you mean than the polygon forming the slope of the pod is passing though the polygon making the side of the helicoper body? Shouldn't intersecting a cube around the whole model remove excess polygons and prevent this?
