ja toll aber wie? Ich bin halt ein Newbie und versteh halt nicht alles wie Ihr. Es steht nichts im Handbuch darüber wie man es umschreibt. Oder ist es mir entgangen?. Kann nicht mal jemand ein Tutor darüber schreiben damit wir als Newbies auch was davon haben?
Ich würde gern so etwas sammeln was funktioniert und dann zu einen Tutorial als pdf erstellen. Hilfe eurer seits vorausgesetzt.
So sieht der Code des plastic.fx Datei aus:
1: Was muss ich ändern/löschen
2. Wie ist der Befehl an die Engine damit sie es versteht

Comments:
A phong-shaded plastic surface. The highlight is done in VERTEX shading --
not as a texture.
