Description

Postprocess GI related settings look like working in 4.22 on Mobile now, but seems buggy, Not sure if it has supposed to be supported on Mobile since it has no any info in Doc or 4.22's release note.

Expectation: it should working like PC, affecting both Diffuse and Reflection.

BTW The Ambient occlusion input in Material does affect both Diffuse and Reflection on Mobile

Steps to Reproduce
  • New a default map and put staticmeshes with a reflected material(a chrome sphere for example) on the floor, build lighting
  • Put a Postprocess volume and unbound it
  • Switch to Mobile preview(ES3.1)
  • Tweak the Global illumination parameters(Indirect Lighting Color and Indirect Lighting Intensity)
  • You will see the both parameters are working only affecting Diffuse lighting on the mesh, but no effecting to Reflection at all

Have Comments or More Details?
