Particle light module clipping through geometry

Particle lights are intended to be cheap because we expect you to use a lot of them and for them to be relatively small: sparks or flares for example. Rendering dynamic shadows for hundreds of lights would be impractical from a performance POV.

I can see a case where you would want to use a single light (an explosion for instance) where you just want the convenience of editing it in Cascade rather than using blueprint and for a single light having the option to cast shadows would be useful. I’ll add it to our backlog to consider for future features.

I’d really appreciate that. It would definitely be a useful addition.

Do you treat each particle as a light source? Why not use a proximity-based volume / cluster to dynamically reduce the amount of light sources in the equation?
