I am trying to do some collision detection.
I have this working for all my terrain, and most of the buildings.
Certain models, have certain polygons, that won't intersect.
I have checked the following:
Bounding box of GSET is good.
ISECT_MASK is good
Bounding sphere of Geode is good.
polygon vertex order is correct (ccw)
normal is correct.
Still there is no intersection with certain polygons.
This accounts for about 5% of them. The rest work fine.
I turned on the option in the segset stuff, to intersect with the geode (bounding sphere), and so it intersects with it just fine.
Of couse, it looks like it is intersecting with air, so I need the tighter test.
This is Performer 2.2.x, where x is something greater than 10
We are running on an onyx2.
Any suggestions?
