Steps to Reproduce

  1. Create Building Static Mesh Blueprint Class
  2. Add InstancedStaticMesh
  3. Change Scale of ISM
  4. Add element to instances array
  5. Translate Instance

Expected Result

Each instance of the ISM translates as intended.

Observed Result

The instance translation is multiplied by the scale. So if the scale of my ISM is set to 1.1 and I want to move the instance to 128.0 on the Left axis, the instance is instead moved to 140.8 on the Left axis (1.1 x 128.0 = 140.8).
