Challenge 06: Chipped Paint Metal! After the ultra-rare case of a beer foam shader last month, it is now time to create something more approachable which comes up quite regularly in production shading. I'd like to thank Maxime Roz for open-sourcing another one of his fantastic HDR's for this challenge. Once again, there will be aÂ voting panel of industry experts in lookdevelopment - working at Pixar, ILM and Double Negative.The deadline of the challenge is on the 1st of October, 00:00 GMT. Good luck everyone!
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 rotate it in these axis: [0, -70.0, 0].
The default lighting setup should look like the following. I added in some spec to validate the rotation of the HDR since there's no hard shadows.
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?
This month, only one render needs to be submitted. 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. Please, also share your scene file if possible. This is not a requirement, but would be very nice. 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. I don't want to limit anyone's amazingly capable brains.
Feel free to post WIPs in this thread.

That's all! The winner gets picked by the admin team on the 1st of October, 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!
