flipped polygons will have duplicate centroids - therefore they violate the BSP data constraints


whoever created the transparency feature obviously doesn't know how BSP works... or forgot to think about it

polygons with duplicate centroids and then having points superimposed on each other will be deleted -- that's REQUIRED for it to be BSP'able

if you want to do "two-way-transparency" you're going to have to slighlty offset the faces -- 0.01 should do it, but you will have inefficiencies in the bsp, 0.1 would do it better (still inefficiencies, but less)

So basically the model will convert properly if I simply make the inner faces slightly smaller than the outer ones? And I won't have to open it up in Truespace?
Ok, so why does it work then if I import to pof, export to cob, open it up in Truespace, save it from Truespace, and export it back to pof (I don't recall it working if I did not FIRST export to POF, then from POF to COB).

[Kazan]

no - you have to move them - if the centroid is the same then the polygons are the same as far as the BSP tree is concerned

import to pof? with what program? cob2fs2? he 'fudged' a lot of things and that's why collision doesn't work ,etc

Cob2FS2, yes, or Modelview (which uses a derivitave).

"inner faces slightly smaller" from a modeling perspective simply means scaling all of them down together; the result would be an offset so it would actually be fine.  Wonder why my jump node works though.

[Kazan]

it wouldn't result in an offset of the centroid

if your jump node is the one being used - it's because the two faces are at an offset

I'm positive I actually converted a model with dual-faced identical polys with PCS, though.  The Orc, IIRC - the girder subobjects had a crude transparency on them, so I made all polys on them effectively 2-sided.

So how could I fix it Kazan, if resizing the inner polies won't work?

[Kazan]

you have the _MOVE_ them, even if slightly
