Using VSM and Distance Field Shadows on the same scene results in missing shadows

Nanite geometry does not cast Distance Field Shadows outside of the clipmap range for Virtual Shadow Maps. Non-Nanite geometry does cast these shadows.

1. Download the attached test project and open

2. Observe the two pillars. The green pillar is Nanite, the red pillar is not.

3. Enter the console command "BugItGo 10509.329113 24773.398377 4882.640179 -21.399900 -858.598190 0.000000"

4. Observe the shadow from the green Nanite pillar is cut off, and the shadow of the red non-Nanite pillar is not.

5. Observe the following settings on the directional light:

• Dynamic Shadow Distance: 0

• Distance Field Shadow Distance: 100000

• Distance Field Shadows: True

• DistanceField Trace Distance: 100000

6. Observe that "r.Shadow.Virtual.Clipmap.LastLevel" is set to "13", and this cutoff matches the cutoff of the shadow from the green Nanite pillar.
