A licensee has reported that they are unable to use an emissive material utilizing the SkyAtmosphereLightIlluminance material expression together with Nanite and Lumen. The linked UDN has some more details on the test setup and findings of the licensee
1. Open the attached test project (Can be found in linked UDN)
2. Turn on the Lumen Scene visualization (r.Lumen.Visualize 4)
3. Observe emissive light contributions coming from the emissive plane
4. Enable Nanite support on the mesh of the emissive plane
5. Observe that no emissive contributions are coming from the plane
