I'm running Performer1.2alpha99 on an Onyx RE^2 (running Irix
5.2-ALPHA-1010931841).
In Multigen our Intensity Alpha sky texture looks nice, but when we are
running our database in Performer the skies looks like they are layered.
It is the Alpha part of the texture which is layered. There are just a few
transparency levels.
In Multigen I tried to change the Internal format, from the default format
to TX_IA8. Then I would still have a full speed texture, but with 256 levels
of Alpha.
Again I tried to run our database in Performer. But still there where just a
few levels of transparency.
At last I changed the internal format to TX_RGBA12 on the sky texture in
Multigen. Then I would have 4096 levels of Alpha. (The only difference was
that the Intenity part of the texture became blue in Multigen.) In Performer
the Intensity part became blue (as in Multigen), but there where still just
16 transparency levels.
The last test is an indication that this problem has no origin in LoadFlt,
since the Intensity part of the texture became blue in Performer.
My question is:
Doesn't Performer allow you to have Intensity Alpha textures with more than
16 transparency levels.
If Performer allows more than 16 transparency levels:
What can I do to get skies with more than 16 transparency levels
TX_IA8 (256 transparency levels) will satisfy our needs for credible skyes.
