Masked Materials have become more expensive in 4.13 and internal builds than in 4.12.

Images attached for demonstration along with test map using the bush prop from starter content.

Tested with builds:
4.12.5 CL-3039270
4.13 Preview 2 CL-3088355
4.14 Dev-Main CL-3092283

Steps to Reproduce

1. Created or use an existing masked material applied to a static mesh
2. Use the foliage tool to paint some around the level or place them manually
3. Switch to the Shader Complexity view mode

Regression: Yes

Results: Shader Complexity view shows masked materials as more expensive than in previous versions

Expected: Shader Complexity for masked materials should not be as expensive
