Can we somehow render only the shadow of smoke simulation in Cycles?
I have lights, shadow catchers and smoke (domain and emitter). When smoke itself is visible, all is fine, we have a deep dark shadow of it: pic 1.
But when, e.g., I turn off camera visibility in domain Cycles settings, shadow disappears as well as the smoke does: pic 2
So, are there any ways to render the correct shadow without rendering smoke which causes it?
