Transformation Matrix Node

Description

Defines a constant Matrix 4x4 value for a common Transformation Matrix in the shader. The Transformation Matrix can be selected from the dropdown parameter.

Two output value options for this node, Inverse Projection and Inverse View Projection, are not compatible with the Built-In Render Pipeline target. When you choose either of these options and target the Built-In Render Pipeline, this node produces an entirely black result.

Important

The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to URP and Render pipeline feature comparison.

Ports

Name Direction Type Binding Description
Out Output Matrix 4 None Output value

Controls

Control Description
(Dropdown) Sets the output value. The options are:
  • Model
  • InverseModel
  • View
  • InverseView
  • Projection
  • InverseProjection
  • ViewProjection
  • InverseViewProjection

Transformations

All these matrices are float4x4 type, and are column major.

Name Value
Model Current model matrix. Transforms from Object to World space.
InverseModel Inverse of the current model matrix. Transforms from World to Object space.
View Current view matrix. Transforms from World to View space.
InverseView Inverse of the current view matrix. Transforms from View to World space.
Projection Current projection matrix. Transforms from View to Clip space.
InverseProjection Inverse of the current projection matrix. Transforms from Clip to View space.
ViewProjection Current view * projection matrix. Transforms from World to Clip space.
InverseViewProjection Inverse of current view * projection matrix. Transforms from Clip to World space.
