Data Types


There are a number of Data Types in Shader Graph. Each Port on a Node has an associated Data Type that defines what edges can be connected to it. The Data Types have colors for usability, these colors are applied to ports and edges of that Data Type.

Some Data Types have associated Property Types for exposing these values to the Inspector for Materials that use the shader.

All Vector types can be promoted or truncated to match any Vector type Port. This behaviour occurs only when the Port in question is not of type Dynamic Vector. When truncating, excess channels are simply removed. When promoting, the extra required channels are filled by default values. These values values are (0, 0, 0, 1).

Dynamic Data Types

Some Data Types are dynamic. This means a port using these Data Types can change their underlying Concrete Data Type based on what Data Type is connected to it. By default, Nodes using dynamic Data Types can only have one Concrete Data Type, meaning that once a connected edge has applied its Data Type to that port, all other Dynamic Data Type slots of that Node will apply the same Data Type.

One notable exception to this is the Multiply Node which allows both Dynamic Matrix and Vector types.

Dynamic Vector

The Dynamic Vector type allows connected edges of any Vector type. All connected edges are automatically truncated to the type with the lowest dimension, unless the lowest dimension is 1, in which case the Vector 1 is promoted.

Dynamic Matrix

The Dynamic Matrix type allows connected edges of any Matrix type. All connected edges are automatically truncated to the type with the lowest dimension.


The Dynamic type is a special case. Nodes that support it must define how it is validated. In the case of the Multiply Node, it allows connections of any Vector or Matrix type, ensuring the correct multiplication is applied depending on the mix of Data Types.
