When using the BumpOffset node, it will produce incorrect resultsi if the Texture Coordinate Index is not 0.

Found in 4.20 CL# 4369336. 4.21 CL# 4613538, 4.22 CL# 4751672

Steps to Reproduce
  1. Open the Editor
  2. Import the attached FBX
  3. Create a material like the attached image but set the TextureCoordinate Nodes Coordinate Index to 1
  4. Apply the material to the imported mesh

It appears the BumpOffset node is still partially relying on Coordinate Index 0


Incorrect Behavior would not occur when the Coordinate index is above 0
