Translucency and GI

Hi all,

I’m reasonably new to realtime lighting. More of a Redshift guy myself. So I’m trying to achieve a look like this, where light travels through Plexiglas glass onto a wall. Is this achievable in any way at all? I currently have no shadow from my translucent material.

Worst case scenario that I bake a light map from Redshift and import it somehow.

Cheers all,
