Description

There is an issue occuring where TransformVector node break compilation material instance but primary material is successfully compiled. When using a custom node to set the value this node intends to do, there is no issue and the expected result can be achieved. This does not appear to be a regression.

Steps to Reproduce

  2. Open Test_M and Test_MI and make sure each are compiled
  3. In Test_MI Check the box for "Rotate UV 90"
    Result: Material instance now produces an error and cannot display correctly
    Expected Result: Material Instance Does not display an error
