Light Complexity Viewmode shows reduced overlap on lights configured with IES Profiles, is this accurate?
Distant shadows - what do you recommend for long range open world shadows, are Distance Field shadows expected to be the most performant? Far shadow Cascade(s) also needed?
Light channels with/without Lumen: Is light channel support planned for Lumen? Currently, disabling light channels on an atmospheric directional light preserves the atmospheric influence, which can be used with lumen to add ambient light, is this technique viable or is it breaking anything, or costing a lot?
We know Lumen doesn’t support “translucent” materials but is this specifically the translucent blend mode? what about Additive, others. if we wanted to explore using additive shaders for fake distant light effects or something, would this conflict with Lumen?
