1) I do a projected-texture on a cube. The texture is "aimed"
        exactly on one face, but it is projected on the other-faces also,
        as if the cube was transparent (it is not).

        how can I solve this problem ??

     2) for transparency, I do:
    
gstate->setMode(PFSTATE_TRANSPARENCY,PFTR_BLEND_ALPHA|PFTR_NO_OCCLUDE);
         gstate->setMode(PFSTATE_ALPHAFUNC, PFAF_NOTEQUAL);
         gstate->setVal(PFSTATE_ALPHAREF, 0.0f);

         what happens is that when alpha < 1, there is no blending, and
         the polygons that are on the other side of the "current" polygon
         are seen as if "current" polygon is COMPLETELY transparent. If
        there is no geometry behind it, "current" polygon is seen.

         anyone knows the soloution ??

     3) when I use SpotLight on the ONYX RE2-R10000 (running IRIX 6.2),
        the whole scene becomes corrupted with red polygons... the same
        code works fine on the indy's that run 5.3.

        could it be a bug of IRIX 6.2 ?? of ONYX RE2-R10000 ??

     The machine I work on is an ONYX RE2-R10000, IRIX 6.2

      Tnx
