     Hi, thank you for looking at my question.
     These days I use Performer on O2 to do some work of virtual
reality.
And I want to make some faces be transparent. I have some rgba files
like
*.rgba. And I use pfLoadTexFile(pfTexture *tex,char *fname) to load the
files. But it doesn't work, seeming that it can just load rgb file. But
I want to transparent parts of the texture. And I have succeeded
transparent
parts of the texture using pfTexImage(pfTexture *tex,unit* image,int
comp...)
by setting comp = 4. But I think loading rgba files is easier. How can I
load
them directly and also get their transparent attribute.

   thank you!
