RSSY 3Delight And Iray To Filament

Convert 3DL and Iray Materials to make them look better in Filament
Update Environment settings to keep your scene from being washed out
Restore directional shadows by adding a Shadowcaster Light and lengthening Spot Light rays
Add “Flame” Lights – i.e., add Point Lights to replace emissive flame materials so that candles, flames, and fires will cast light and shadows (this can even work to update old 3DL scenes to Iray!)
Replace Ghost Lights* with Point Lights
Update settings for Point Lights and Spot Lights to render better in Filament, such as converting light temperature (which Filament ignores) to its color approximation in the light color (which Filament renders)
See your changes in real-time depending on the complexity of the scene!
