Hi UE friends - I’m getting into the HDRI Backdrop ray-traced lighting strategy but have run into an issue. Initially shadows were rendering properly on the ground-plane/environment dome but, while following the recent UE4 Automotive lighting/rendering tutorial ( Learn About Photoreal Automotive Rendering in Unreal Engine | Webinar - YouTube ) the shadows disappeared.
I tried backtracking on the steps I had taken but nothing brought them back and, even after starting a new project from scratch, I haven’t been able to get the shadows to reappear…
In the “Lighting Only” view, there ARE very soft shadows being cast by the HDRI backdrop itself and adding a directional light adds a much clearer shadow that should be visible on the HDRI backdrop mesh.
However, in the Lit scene but no shadows of any kind are cast on the ground…
Has anyone else run into a similar issue? I’ve double checked that all lights are movable and reset all the settings I could think of or had changed but with no success. Any advice would be a huge help!
