If you are using a cliptexture configured with:
int_format PFTEX_RGB5_A1
ext_format PFTEX_UNSIGNED_SHORT_5_5_5_1
img_format PFTEX_RGBA
and some of the texels in the tiles have a 0 alpha bit, what do you
have to do to make those texels render as transparent? I am using this
in the context of a spherepatch3 -- I would like to be able to see through
the spherepatch to what is underneath. I tried loading the spherepatch3
with the texture set as /usr/share/Performer/data/tree.rgba (a tree
billboard texture that has transparency in it) and then running through
all the spherepatch3's geoset geostates and doing a
gstate->setMode(PFSTATE_TRANSPARENCY, PFTR_ON);
but that doesnt seem to work.
any ideas? thanks
