[Plib-users] Transparent texture

[Paolo L. <p.l...@ci...>]

Why in SSG my transparent (rgba/inta) textures appear with a sharp
transition from alpha=255 to alpha<255, like 1-bit alpha?

Better explained, whilst alpha channel is fully exploited (i.e. [0:255]
range), transparent area on such textures is limited to where alpha is 255.
This obviously results in a bad "halo" where, let's say, 0<alpha<255, and
effects like steam, smoke are thus impossible to be done thru textures.

Should I enable some special flag in the state node? (the image loader
correctly understand the zsize 2 or 4 of such textures).

Paolo
