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.
