Casting object shadows on Afterburn

[emil_vfx]

Hello!

I am trying to cast shadows on Afterburn coming from objects in the scene. For rendering I use Vray. Although I've checked Receive Shadows, Cast Shadows and Self Shadows, I do not see any shadows from the object on Afterburn (Raymarcher). For the light (Free Direct) I use Vray Shadows (AB Shadow Types were also tested, no desired result), Atmospheric Shadows ON. The object casts shadows (option on 'properties' checked).

Any solutions???

Thanks!
