Solid + Presets

Switch to Solid Shading with a quick access to a selection of presets:

• Default: Blender's default Viewport Shading settings

• Cell: flat colors set to material so it detects your materials viewport colours with shadows enabled - very powerful in Workbench Rendered with the compositor enabled

• Unify colors (only visible with the Cell Preset selected): detect all your material colors in your scene, sort them in a limited range of primary colours, and apply those colours to your material's viewport display colors, simplifying your scene's colours for a more balanced loook

• Alias1, 2 3 and 4: Alias most famous shaders

• Red 1, Red 2, Fuel: other hard surface friendly shaders

• Clown: similar to Keyshot's Clown pass. Use this preset in Workbench Rendered to render a high-resolution Clown pass of your scene.

• User 1: customizable user profile. To set it up, set the settings of your choice via the Viewport Shading Panel, then click "Sync to User". The User1 setting is persistent.
