Description

Volumetric Translucent Shadow has artifacts when using some nodes like noise when clamped between 0,1. This happens with other nodes as well.

When using a basic alpha mask or constant value there is no visible issue.

Attached gif for demonstration.

Steps to Reproduce

1. Open UE4
2. Add any mesh to the scene and set it to cast Volumetric Translucent Shadows
3. Create a new material and setup as pictured. (Noise plugged into Clamp(0.1) into Opacity.
4. Move the camera around the scene to see the artifact

Regression: No

Results: Using the Noise node cause the volumetric shadow to go in and out of being visible.

Expected: Shadow should be similar to simple material with lower constant value plugged into opacity.
