Fuente/ Codesnippets | | | | |  | 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.  |

Yo habe ahora con verschiedenen Programmen una TGA producido.
Lo kommt siempre el Fehlermledung "Falsches Format".
Was es en dir para una TGA y welchem Programa hast du lo producido ?
Gracias.

Lo muss es una unkomprimierte rgba-TGA-Expediente handeln -
puede ser z.B. con IrfanView speichern. |
