This mode can be used for swimming pools and other placid liquid surfaces. Ocean Mesh – The grid content is extended to a flat area, fitting the camera's view. In most cases, this mode is used with a displacement texture such as the Phoenix FD Ocean Texture.Ĭap Mesh – Only the upper liquid surface is rendered. This mode is mostly used for liquids but can be applied to thick smoke using a scattering material or to plumes of smoke to create effects such as large underwater bubbles. Mesh – The content is converted into a standard mesh using the Surface section options. It produces a procedural Isosurface geometry using the Surface section options. Compared to the Mesh mode, the result is always smooth but will take longer to render. Isosurface – Used mostly for liquid simulations.
Volumetric Heat Haze – Produces the same result as the Volumetric option, but adds a heat haze effect when used with the Heathaze parameter. Note that you might need to increase the Max depth of a V-Ray Material with refraction in case it intersects with the Heat Haze shader. Thus, a Smoke simulation can be rendered as a polygon mesh with a custom material applied to it.Īpproximate and Approximate+Shadows options for the Scattering parameter in the Smoke color window are not supported in Volumetric Geometry mode.įor a complete list of the supported Render Elements in both Volumetric and Volumetric Geometry mode, please check the Render Elements page. The V-Ray Volume Grid also provides you with the option to generate a mesh surface based on any of the supported channels. Unlike the volumetric modes, surface modes have no dedicated shader they use the material applied to the Volume Grid. The surface modes can be used for some interesting fire-related effects, like freezing flame or cartoon-style smoke. Cinema 4D materials can't be used to shade volumetrics, so their shading is described in the Fire , Smoke Color and Smoke Opacity rollouts. The volumetric modes are used for fire and smoke. The Volume Grid is able to operate in multiple rendering modes that can be divided into two main branches: volumetric and surfaces (Isosurface, Mesh, Ocean Mesh and Cap Mesh). All parameters necessary for rendering a Fire / Smoke simulation can be found under the Rendering roll-out and its sub-rollouts.
Overviewįor convenience, the shading and rendering of Volumetric effects (Render Mode: Volumetric, Volumetric Geometry, and Volumetric Heat Haze) are handled by the built-in Volumetric shader of the V-Ray Volume Grid. This page provides general information about the Rendering tab of the V-Ray Volumetric Grid.
