PBR material with no shadows

[LimeSim]

Hi!

Is there a way to deactivate shadows for PBR materials? There's a tag for that in P3D materials, which seems to be missing for PBR materials. Also I couldn't find anything that lets me deactivate shadows through LUA scripting.

I would like to remove shadows from materials for the following uses:
- billboard grass
- highly complex 3D terrains that will need to be placed above the actual terrain

Bests,
Sascha
