QAEntry FallenSmall_x0_y0 Landscape Rendering Black

I was working through the WorldComposition_ImportTiledLandscape_Edit test and noticed that this rendered black. There might be a problem with the landscape layer data.

This is a regression from our last regression pass Main CL 3148839

1. Open QA Game > QAEntry
2. Open the World Settings - WIndow > World Settings
3. Enable World Composition
4. Open Levels - Window > Levels
5. Search FallenSmall and select all 4 FallenSmall levels
6. Right Click and select Load
7. Locate the landscape in the viewport

Result: FallenSmall_x0_y0 landscape appears to render black

Expected: The landscape is colored in the viewport
