1. The main reference image must be selected from one of the 750+ images on the Mattershots Instagram inspiration channel.

Because of the image resolution limitation on Instagram, if you need more information about small surface details for example, you can use additional images as references (of the same type of material) you find on the web to enrich your work.

If you use additional reference images, please include them in your submission zip.

2. You don’t have to reproduce the Mattershots scenes.

Let’s focus only on the material. No need to make 3D models or UVs, create a scene, et cetera. These elements won’t be taken into consideration during the judging phase.

However, if you want to go further in the development of your submission, we’d be happy to have a look.

3. The materials must be created in Substance Designer.

You cannot simply import bitmaps that have been created in another tool.

4. Materials must be tweakable.

With Substance Designer you have the possibility to expose parameters to tweak several attributes of the materials such as color, structure, glossiness, size, distribution, etc. Show your creativity!

5. Entry mode.

Select a material reference from a single image from Allegorithmic’s @mattershots inspiration channel on Instagram and use Substance Designer to create/reproduce the material textures. You can use an existing texture from Allegorithmic’s Substance Source PBR material library to get started but it is not a requirement. We strongly encourage contestants to post their work in progress in our dedicated forum where the community has proven in the past to be prompt to help and give constructive feedback on submitted WIP entries!

6. You must submit your entry in ONE, and only one, of the two contest categories: General or MDL.

Categories will be judged separately with winners in each category.

7. You can submit only one entry (and in only one of the two categories).
