Title says it all. I’d love input on what upcoming shader challenges you would like to see. Use the post voting system if you agree with someone else.March 15, 2017 at 10:15 pm #1180
some time ago I was trying to create a realistic, used car tire with these white fonts of goodyear or something.
but it never really looked good.
so my idea would be a used, realistic car tire shader. 😀This post has received 1 vote up.March 17, 2017 at 5:03 pm #1260

Meat could be an interesting shader!This post has received 1 vote up.March 17, 2017 at 7:00 pm #1266

Dirt, Mud, Cracked Concrete, Water, Fire etc. 🙂
Are you planning on using the same scene setup for the competitions? Would be a big help for those of us converting it into a realtime engine – takes a while to get all the relevant things set up.This post has received 2 votes up.March 17, 2017 at 7:56 pm #1268
No, the other challenges will be with different models. Light setup might stay the same.March 17, 2017 at 9:02 pm #1270

Ooh I love Arianna’s idea of meat! Anything food related would be challenging, like a hunk of sweaty swiss cheese.This post has received 1 vote up.March 18, 2017 at 8:21 pm #1301
@Markus I agree with the car rendering 🙂 me too I was rendering car once and it’s really bad long time ago.March 19, 2017 at 1:57 pm #1319

I thought the snowball was a nice starter as it is difficult to get right; great for discussion.
Something that might be equally difficult, could be a piece of Coca Cola candy perhaps?March 19, 2017 at 8:44 pm #1331

Going from Snow to Ice would be logical 😉March 24, 2017 at 1:16 pm #1452

We can try to recreat a realistic car paint with flakes! And we can use the Speed Shape made and shared by Jeff Patton http://jeffpatton.net/speed-shapes/

I would love to see how people manage to recreate an iridescent shader, such as a pearl or a shell, there are probably many ways to achieve it but it’s hard to get it right

It would be interesting to replicate some kind of headphones foam. I had to do it when I was studying, with ones that had some smooth shadow/light balance and small spotty highlights everywhere. Perhaps it’s too similar to the snow challenge, as it’s a plain flat colour however. @juliencrochet, Arnold just implemented a Thin-film like shader in their last build ;>This post has received 1 vote up.March 26, 2017 at 10:51 am #1471
Fantastic suggestions so far everyone! Keep them coming! An iridescent shader has been on my mind for a while, so I think it will pop up in one of the challenges for sure. @juliencrochet, Arvid did a great tutorial on it recently (for arnold) https://www.youtube.com/watch?v=aSsEHFA4bqkThis post has received 1 vote up.March 27, 2017 at 10:03 am #1497

Thin film really does look nice !
The same can be done with a third party shader on VRay ( https://www.sigershop.eu/free-3ds-max-plugins/sigertexmaps-thinfilm/ ), but i guess the difficulty would be finding the right blend between the colors along the shape, and the right amount of translucency 🙂March 27, 2017 at 11:47 am #1498

A lava ball could be interesting to do also , something like this 🙂March 27, 2017 at 8:22 pm #1503
Going to add to the idea iridescence and say Bismuth crystals. The geometry is cool and the angles lend itself to show off the different colors. Plus you are not bound to a specific color range since that depends on how the oxidation layer is formed.This post has received 1 vote up.March 28, 2017 at 6:27 pm #1516
can we append lighting in his general means as challange as well to the site? i think it can be great as well doing light studys together, since zeno providing us a great plattform btw thanks for the effort
i am also in for ice as next and would love to joinMay 2, 2017 at 12:36 pm #2586
I would suggest something like milk, orange juice and the like.. its actually much harder to do than some might think. Keeping in mind all features like higher transmissiveness in thinner areas, sss with caustics, colorchange for orange juice towards greenish in thinner areas as well. Or meat, with fat veins etc, procedurally..May 2, 2017 at 4:37 pm #2598

Basically any material that has a really tricky component to it would make for a great challenge.

- Molten materials like glass or lava. On hot glass we’d need to get the reflection, refraction, and emission all just right, on lava we’d need to get a stone shader and a molten shader working, and a pattern for the crust.
- Iridescence, like others have said. Pearls, beetles, shells. Hot or freshly welded metal could combine anisotropy, iridescence, and blackbody emission.
- Almost any food you can think of could be difficult to get right. Raw meat, slice of watermelon, toasted cheese, a potato.
- Car paint is a classic challenge. Maybe spice it up by making it slightly worn or muddy?
- Since correct shadows proved really hard to get on the candy, maybe something like a jar of cloudy pond water would make a good challenge. Refraction, reflection, complex roughness, multiple interfaces, volumetrics, and some caustics for good measure.

A lenticular shader would be very interesting. This material changes based on the glancing angle due to micro changes to the elevation and color.
Here’s an example. It might be interesting to try this without using cheats like facing ratio.This post has received 2 votes up.
