OpenSim (O)RM Map Generator

[Manfred Aabye]

OpenSim (O)RM Map Generator
ORM Materialien spiegeln die eigenschaft eines Materials wieder.
Beispiel: Jeans Stoff kann für mehrere Jeans, Schuhe oder Mobillar genutzt werden egal welche Farbe diese Objekte haben es zählt nur die Grundstruktur.

Funktion: Programm starten - Ordner auswählen der Texturen - von zum Beispiel freepbr enthält - dann generieren - und sie werden alle gespeichert.

Python Beispiel:

PHP-Code:
