[Plib-devel] disappearing texture problem

[<ke...@fl...>]

I've seen the disappearing texture before using a Rage Pro - 
then took the same app to another Mac with a Rage 128, and the 
textures appear.  Just got to have the texture memory on the 
card...

We added some code to SGI loader so that it always used an alpha 
channel,
even if the SGI file didn't contain an alpha channel. Otherwise, 
the texture
doesn't display, seemingly getting skipped by the renderer. For 
example, in
the opening screen of tux, there is just the water texture at 
the bottom,
tux's feet, and other things that contain alpha channel.

To better illustrate, here is a screen:
