VRay 3.4 is out !

Recommended Posts

Il y l'ajout du denoising ! 

Je n'ai pas essayer sous vray, mais sous corona cette option est géniale !

Je download de suite vray 3.4 pour tester ça :)

 

D'autres nouveauté ou amélioration dans cette build ?

Pourquoi ?

Bah parce que Chaos Group a emboité le pas de Render Legion sur l'intégration d'un système de denoising, j'imagine.

Sans retirer le moindre respect pour le fantastique boulot abattu par Render Legion, je ne peux m'empêcher de sourire quand je vois comment certains (pas que Roland, pas que sur ces forums d'ailleurs) dénigrent à présent VRay ...

Moi aussi j'avoue que j'ai du mal à comprendre: en tant qu'artiste ce qui m'intéresse c'est de constater que les compagnies qui mettent au point les moteurs de rendu se tirent la bourre pour les faire avancer et nous faciliter le travail au quotidien. Après, peu importe qui fait quoi avant l'autre du moment que le mouvement général va dans le bon sens et je me félicite que Chaos ait mis au point un denoiser pour VRay.

Moi ce qui me fait marrer c'est ceux qui pensent vraiment que coronna et vray jouent dans la même cour en fait...

Le denoising, on le trouve aussi dans renderman par exemple, et les settings super simple, arnold le fait depuis.. euh... avant même que render legion existe ?

Wouah c'est beau :D

Le truc qui m'embête pour le moment c'est qu'il n'est pas possible de récupérer les passes denoisées, seulement la beauty. Tant que la post prod derrière est pas trop lourde ça va, mais je trouve ça dommage. Je vais en parler à Vlado.

Oui les gains de temps sont très intéressants. Tu ajoutes juste le RE VRayDenoiser et VRay te calcule la RGB habituelle + la version dénoisée. Tu as différents presets: Mild, Default, Strong et Custom. Avant de lancer les calculs tu choisis le type de denoiser: soit VRay ne traitera que la RGB, soit il traitera distinctement les render elements qu'il fusionnera ensuite pour créer la RGB dénoisée. Cette dernière option est plus lente mais préférable car il y a moins de risque de dénoiser les détails de certaines textures. Le résultat peut être mis à jour après calcul avec le bouton Update: donc tu peux toujours choisir un preset moins fort si l'effet lisse trop l'image.
