Salut
J'ai trouvé quelques explications sur les compositor ici :
http://www.ogre3d.org/tikiwiki/Composit ... tive_bloomDu coup, j'ai testé ça avec l'exemple 3D bridge, mais je ne sais pas comment ça marche en purebasic, il manque un exemple dans les exemples 3D
.
Il faut placer ce fichier dans le répertoire des exemples 3D de purebasic.
