Shaders

Shader Parameter Driver

MonoBehavior that automatically drives shader parameter inputs based on a referenced Transform. Can be used to more consistently animate shaders via animation or interaction.

Targets - Specifies a list of shaders to drive, when given a Renderer target and corresponding material index.

Drivers - Specifies a list of shader parameters and how to drive them.

• The Parameter field specifies the name of the shader parameter. The name is automatically prefixed with an underscore during processing.

• The Driver field specifies the Transform to drive this parameter with.

• Value specifies what spatial data value should be taken from the object.

  • Position specifies the driver’s position. W is always passed as zero.

  • Rotation Euler specifies the driver’s rotation in Euler Angles, in degrees. W is always passed as zero.

  • Rotation Quaternion specifies the driver’s rotation as a Quaternion.

  • Scale specifies the driver’s lossy scale. W is always passed as zero.

  • The Type field specifies what data type is used to drive the shader.

    • Float passes the length of the vector.

    • Integer passes the length of the vector, rounded to the nearest integer.

    • Vector passes the vector with up to 4 coordinates (XYZW). It can be used for any vector type parameter (Vector2, Vector3, Vector4).

• If Local Space is checked, the value is automatically converted into the target renderer’s local coordinate space. Otherwise, the value is always in world space.
