well it lookes fine on nvidia cards,, with
scr alpha or inv src alpha etc etc.
but on the g400 matrox cards, the sorting doesn;t
go wrong, but the alphas invert depending on the distance,, very weird , so
they may seem alright nearby but when you zoom out the go inverted.. or the
other way around, i can't find logic to this.
maybe i used the wrong blend modes . modulate
alpha also doens't always give the desired effect and sometimes using modulate
with source alpha works fine, it occus mostly in a scene with many
alpha's like a forest..
also just setting the blend value to 254 or lower
seem to help also..
so there, i find it very strange as
well.

when you say it does not work what do you meann
?? wrong object display sorting ???
the blend mode for alpha is modulate alpha, src
alpha, inv src alpha
should work evrywhere except on the CRAPPY ATI
rage pro ......

Hi everyone,
I've noticed tht the nemo player handles
alpha blend modes differently on various chipsets.
especially when there are multiple materials
with alpha blends in a scene.
the problem occurs on matrox 3d cards, and
3dfx based cards,
since where developing on nvidia chipsets its
not always imediatly clear if an alpha is gonna work on a different
machine.
has anybody got experience with this., i
can't seem to find a proper mode which works on different
cards.
but the matrox and 3dfx cards seem to have
the same way of handling alpha's could that be correct..
regards
tomas
