|  | Juhu Transparente Texturen - c'est mir gelungen 
TGAs peut une 4 layer (transparentslayer) beinhalten - XProfan peux mais aus cette TGAs aucun Texturen erzeugen quelle aussi encore transparent sommes.
Wofür?
Wände avec Lücken? un balle avec rauer surface? Highmap via Bitmap?
ou bien: 2D-Sprites per OGL?
Licht et Partikeleffekte?
eh bien bau je encore une deux tools zum Sauver cette TGAs - et ensuite peux aussi chacun quoi avec anfangen.  |
