    Hey, I’m a game dev who does shader programming for Unity. New to offline rendering, but this challenge was really intriguing.

    Ended up learning a lot very quickly about Blender and Cycles, but the result is not really as I’d liked it to be.

    The textures were kindly made by my friend Julian Fisher in Substance.

    The project repo is on github.

    I wanted to write my own brdf (as I would in a realtime renderer), but sadly Renderman 21 doesn’t have that any more. I though Cycles with OSL did, but found out I was very mistaken xD

    In the end I used @anthonypilon‘s normals change, the cycles glossy GGX, this thin film implementation, and this layer implementation.

     

    And the animation: https://player.vimeo.com/video/219877182

    “when trying to wrap that geo around the model, the cubes got skewed too much and they lost their retroreflective property. I couldn’t see a way around this”

    In C4d it’s exactly what the mograph Matrix object does (wrap without deform cloner Objects). It must probably have an equivalent in Mash.

    @fred, good tip, but in this case that would cause the cubes to overlap, which would cause more artifacts.

    WINNER ANNOUNCEMENT!

     
    This one was without a doubt the most interesting challenge so far and personally, I learned A TON. Thanks to everyone who participated and therefore helped grow this community this month.

     
    As promised, the challenge has been judges by multiple industry professionals this month. The judges are Arvid Scheider (ILM), Harsh Agrawal (Pixar) and Henning Sanden (MPC).

     
    Arvid’s and Harsh’s top 3:

    1. Anthony Pilon – @anthonypilon

    2. Zeno Pelgrims – @admin

    3. Oleksi – @alkova06, due to the added technical challenges of doing this real-time.
    Henning’s vote was for Anthony as well.

     

    The winner is very clear in this challenge, @anthonypilon. Both on a technical level and creative level, it stands out. You thought us all a ton of stuff here! Send me your address so I can send you your shirt : D

    This challenge was a lot of fun, glad I could help people learn from it. I’m looking forward to playing with light scattering again on the raspberry 😛

    @admin is there a PM system on the forum? I can’t seem to find it

    I didn’t find the time to finish, but the most important was to participate, at this superinstructive and nice challenge.

    Thanks Zeno…
    …and anthony of course 🙂
