Répetition de texture

[chakourireda]

bonjour,

voila je rencontre souvent le problème de la répetion de texture sur des grandes surfaces, et j'ai rechercher sur le net mais sans succès, et voila je suis tomber sur ce tuto "https://www.youtube.com/watch?v=dvpTjaBrkTU&t=277s" mais pour le moteur de rendu redshit ou il utilise le noeud "osl" avec un code source, quelqu'un peut m'aider comment l'utiliser avec arnold ou bien me proposer une autre solution,

Merci par avance

Hi!

There are many ways to break up the uniformity of texture repetition, but one of the easiest in Arnold is probably to use the Triplanar node. Using its Cell option, you can scramble each "tile" and it also has a master Blend attribute that blends between the tiles (see example below). Another way that should work is to use the UV Transform node and feed it some random data in the e.g. Scale, Translate, and Rotate attributes. The UV Transform has a Noise attribute that you then use to "mess up" the UV coordinates for a non-repetitive pattern.

I'm sure there are other ways as well! Good luck!

I'd also like to add that you can use any OSL shader in Arnold as well. It's very similar to Redshift, there's an osl shader where you can copy & paste the code. Or just copy the .osl file to the C4DtoA/shaders folder. More info: https://help.autodesk.com/view/ARNOL/ENU/?guid=arnold_for_cinema_4d_ci_Shaders_ci_Third_party_Shader...
