Rock Generator 2.9.0: Vertex-Farb-Layout v2 (kanal-getrennt)
Nach Wunschliste des Users. Attribut "Cavity" traegt jetzt drei UNABHAENGIGE
Masken statt einer eingebackenen Mischung:
R = Cavity pur 1 = offene Flaeche, 0 = tiefe Fuge - OHNE Hoehen-Verlauf
G = Moos/Schmutz aus Oberseiten-Anteil + Fugennaehe + Noise, mit Reglern
fuer Menge, Aufbruch und Seed
B = Hoehen-Verlauf 0 = Unterseite, 1 = oben, separat
A = 1 (Reserve)
Der Punkt: Boden-Saum und Moosfarbe entscheidet jetzt das MATERIAL pro Instanz,
nicht mehr das Mesh. In v1 steckte der Verlauf fest in R und liess sich nicht
mehr trennen.
Gemessen: R ohne Hoehenabhaengigkeit (unten 0.62 / oben 0.59 - vorher war das
der eingebackene Verlauf), B steigt 0.08 -> 0.92, G oben 0.57 vs unten 0.20,
A konstant 1.00. Moos-Seed aendert die Verteilung. Alle drei Kanaele ueberleben
den FBX-Roundtrip.
tests/test_vertex_cavity.py prueft jeden Kanal einzeln inkl. Roundtrip.
