District 9 - Render Passes

Notre confrère propose un papier sur le workflow utilisé pour la post-production du film District 9, avec images, textes, et vidéos à l'appui, montrant précisément les passes de rendu utilisées pour atteindre un degré de réalisme avancé.

Extrait en anglais : "Julianna Kolakis first worked on the look development of Christopher and little CJ with James as well as the look dev lead Joe Eveleigh, the lead lighter Robert Bourgeault, and later Anna Ivanova, the second texture artist who came aboard to help with maps for the aliens and other models. The artists all contributed to the character development gathering references and giving artistic feedback on how materials such as the skin, shells, and tentacles should look.

"There were 2026 texture maps for a variety of adult aliens (excluding clothes), and each model had 21 UV maps at 4096 pixels," explains Kolakis. "These maps included colors, bumps, displacements, various specs, wet specs, roughness, masks, multiple subsurface, and reflections for materials such as the shell, skin, eyes, fur, bruising, blood, dirt, dust, war paint, and stickers."

Défragmenter un seul fichier ou un seul répertoire

Pour éviter des catastrophes lors d'accès fréquent via votre logiciel de montage ou de compositing à des séquences d'images ou à des vidéos HD qui nécessitent beaucoup de ressources pour les afficher impeccablement, Microsoft propose via Sysinternals un logiciel appelé Contig, qui s'execute sur Windows via la fenêtre DOS Command (CMD), et qui vous permet de défragmenter les fichiers de votre projet, sans défragmenter tout votre disque. Pour télécharger Contig :

Je vous conseille de placer l'executable Contig.exe dans votre répertoire Windows/system32 pour que vous puissiez y accèder de n'importe ou, sans avoir à la placer systématiquement dans votre répertoire dans lequel se trouvent vos fichiers à défragmenter.

Les commandes sont entre autres :

analyser un fichier et connaitre sa fragmentation : contig.exe -a "votre_fichier"
défragmenter un fichier en affichant les étapes de traitement : contig.exe -v "votre_fichier"
défragementer un répertoire complet en affichant les étapes : contig.exe -v -s "votre_répertoire"
