## Thumbnail-Generator für die Objekt-Bibliothek (Karte t_3a998ae4).
|
|
## Rendert JEDESM Bibliotheks-Objekt einmalig als 128-px-PNG nach
|
|
## library/thumbs/<id>.png — die Bilder werden committed, der Editor lädt sie
|
|
## dann einfach aus der Datei (LibraryBrowser.load_thumb).
|
|
##
|
|
## Ausführen (braucht echtes Rendering, NICHT --headless):
|
|
## xvfb-run -a godot4 --rendering-driver opengl3 --path . --script res://tools/gen_thumbs.gd
|
|
## (auf Slys PC auch ohne xvfb: godot4 --rendering-driver opengl3 --path . --script ...)
|
|
##
|
|
## Exit 0 = alle Thumbnails geschrieben.
