|  | Juhu Transparente Texturen - es me gelungen 
TGAs puede una 4 layer (transparentslayer) beinhalten - XProfan kann aber de esta TGAs no Texturen erzeugen welche auch todavía transparent son.
Wofür?
Wände con Lücken? Ein Ball con rauer Oberfläche? Highmap via Mapa de bits?
Oder: 2D-Sprites por OGL?
Licht y Partikeleffekte?
Nun bau Todavía eins zwei tools para speichern dieser TGAs - y luego kann auch cada qué con anfangen.  |
