Welcome to the legacy site! It's a bit broken, but should work for the most part - just keep in mind I'm not actively maintaining it!

DocumentationReferenceBase→Shells Settings

Shells are copies of the model that grow outward, and can, for example, be used for grass or cartoon outlines.

Note: The Shells inherit most of their settings from other Base settings, such as the diffuse, specular, emission and transparency.
Note: Enabling Shells lets you use the input "Shells/Distance", which is the normalized (0-1) value based on the distance from the base.
Shell Count

The Shell Count defines how many shells there are.


The Distance is how far the shells expand. The shells expand linearly, meaning if there are 10 shells, the 5th shell is half the Distance away from the original model.


The Ease lets you shells collect closer or farther. An ease of zero makes the shells lean closer towards the model, while an ease of 3 makes them expand towards the edge.

Uses Lighting

Changes whether the shell is unlit or not.

Z Write

Changes whether the shell ZWrites or not.


Defines when the shells are rendered, before or after the main model.


Changes which parts of the model are visible. All makes the entire object visible, Front makes only the front facing faces show, and back makes only the back facing faces show.


The blend mode lets you change how the shells are blended. These are similar to the layer blend modes, see here.

Here many transparent shells create a fur like effect.
Only one shell is needed to create a simple cartoony outline effect.
