Node previews in MaterialGraph with Substrate enabled render solid black in 5.6. The latest 5.5 engine does render previews correct with substrate enabled.
1. Enable Substrate
2. Check a material with any node with a preview. Constants or TextureSample are good candidates.
Expected: Node previews render with their result
Actual: Node previews render black
