Challenge 02: candy shaders. Some really interesting light transport happening here! This will truly push the renderers to the boundaries of their capabilities. We want to thank everyone who participated in the last challenge - it was really fun to see so many people submitting their best shot at a snow shader. For what it's worth, we've heard some very positive things from top people in the industry. People are watching and it's a fantastic opportunity to show your skillset to them.
The initial scene setup is very straightforward and only takes 5 minutes. It is important that we standardize scene conditions between contributors, so please make sure that you're not setting up the scene differently.
- Download and extract the .zip package.
- Open or load in the alembic, containing the scene geometry and camera.
- Assign a lambertian material to the floor geometry, assign the checker texture map [tex/checker_floor.tif] to the color slot.
- Repeat step 3 for the macbeth chart [tex/macbeth_chart.tif].
- Create an HDRI light and plug in the provided HDRI. Leave the light intensity at 1. Leave the Y-axis rotation at 0.
A reference images of the default lighting condition can be found here.
Please make sure to post renders using this setup. It is allowed to post extra renders using your own light setup. Since the shared light setup is at the core of the challenge, this will be heavily moderated. You've been warned!
What is expected of you?
The focus of these challenges is on sharing shading knowledge. Explain the shading setup in as much detail as you can be bothered to do. Think of shaders.xyz as a sort of open source project. About creating extra geometry - just try to think if it would work in a shading pipeline. If you think it would be practical, go for it.
Feel free to post WIPs in this thread.

That's all! The winner gets picked by the admin team on the 1st of May, 2017 and will receive an exclusive SHADERS.XYZ t-shirt (hype!). Don't forget to motivate others by voting for your favorite submission! Good luck everyone!
