Hey there!
I am playing around with Niagara and lighting and I made translucent smoke that’s supposed to cast and receive shadows. Now the casting works fairly well with [Translucent Particle Shadow Casting][1] and the shadows cast on the material look rather natural at close range too:
But when the translucent particles receive dynamic shadows from static meshes, the shadows disappear at pretty close distance.
A similar problem has been described but not solved in this rather old thread:
[Shadow on translucent material disappear at distance][4]
Any advice? Thanks and cheers!
