In order to produce correct Render Elements for Fire/Smoke simulations, the Phoenix Simulator needs Render Mode to be set to Volumetric Geometry with V-Ray 5, V-Ray Next and V-Ray 3.
In order to produce correct Render Elements, the Particle Shader needs Render as Geometry to be enabled with V-Ray 5, V-Ray Next and V-Ray 3.
Please note thatParticle Shader rendering is currently not supported with V-Ray 3 GPU and V-Ray Next GPU.
Keep in mind that V-Ray Next or V-Ray 3 Adv. CPU produce correct results with Progressive sampler for Render Elements only when Enable Filtering is on.
Rendering of Fire/Smoke elements with V-Ray Next GPU requires Phoenix 3.12 and V-Ray Next update 1 nightly 28798 (18th December 2018) builds or newer.
