Description

When placed in a vertex shader portion of a material the Object Position calculates correctly for each instance of a instance static mesh.

In the same setup, Object Orientation calculates only the root Actor's orientation.

Steps to Reproduce
  1. Open Attached Project

RESULTS: Instance Positions are calculated in vertex shader with Object position, but Object Orientation is not.

EXPECTED: When passed in Vertex shader both Object Position and Orientation be calculated.
