For V-Ray 6, please refer to the table below to assess whether a Render Element produces correct results when using a specified Render Mode or Particle Shader configuration.
For V-Ray 5, V-Ray Next and V-Ray 3, the Fire/Smoke Simulator needs the Render Mode to be set to Volumetric Geometry in order to produce correct Render Elements.
For V-Ray 5, V-Ray Next and V-Ray 3, the Particle Shader needs Render as Geometry to be enabledIn order to produce correct Render Elements.
Note that Particle Shader rendering is 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.
