VRAYENVIRONMENTFOG CINEMA 4D
Gizmos — A list of atmospheric gizmos and arbitrary meshes within which the fog will be calculated. When no textures are used, VRayEnvironmentFog uses a simple sampling algorithm where samples are distributed according to the volume density. No, create an account now. So i played around with the settings and found out a way to make the clouds more realistic. Filter Color — Affects the color of the inscattered light. Higher values render longer, but with less noise. Fog distance — Controls the fog density.
Gizmos — 4f list of atmospheric gizmos and arbitrary meshes within which the fog will be calculated. The default value for this parameter works fine for surfaces, but for volumes, where a lot of weak light contributions are added together, it may produce a visible sharp boundary where the light calculations stop. Fog vrayenvironmentfoog — If no atmospheric gizmos are specified, the fog vrayenvironmenyfog assumed to start from a certain Z-level height and continue downward indefinitely.
Note that whenever a texture is used, VRayEnvironmentFog will use the ray marching sampler to calculate the fog. Discussion in ‘ User Tutorials ‘ started by YamaDec 1, Note that if present, the texture overrides the specified Color. Higher values make the rendering faster but may introduce artifacts.
Horizontal Flip — flips the reflection Environment horizontally.
While the example is nice for a background, it hardly seems detailed enough to fly through. Affect Shadows — Specifies if the fog should affect shadow rays. Cutoff threshold — this parameter controls brayenvironmentfog the raymarcher will stop traversing the volume.
Note how multiple scattering of light inside the volume greatly increases the realism of the image. This group allows you to override Environment settings for indirect illumination calculations. Note the broken caustics beam – this is not because there are not enough caustics photons, but because we don’t have enough samples for the fog itself.
Brightness — a multiplier for the Refraction env. No, create an account now.
Creating realistic clouds with Vray Environment Fog and Physical Sky
Color — specifies the environment color for reflection. This example demonstrates the effect of the fog color. Simiplify texture for GI — When this option is checked Vray will use a simiplified method for calculating the GI when rednerderin parts of the fog that are textred or are being faded out. The second algorithm is a raymarching scheme, which is used when any of the volume properties are mapped with a texture.
Smaller values for this parameter render faster, but may produce noise in the image. For more information, see The Sampling Parameters without textures example below. Fog color — Defines the color of the fog when it is illuminate by light sources. Subdivs — this parameter determines the number of points inside the fog at which volumetric lighting is evaluated.
The scene for the last image is available here. Affect Refractions — Specifies whether the fog will be rendered in refractions.
This might need to be changed to World XYZ if the texture will be assigned to fog in the scene environment.
The volumetric textures density and emission for this example are provided from a fluid dynamics simulation in the form of 3D textures. The sampler steps through the volume, evaluating volumetric textures and lighting, until it leaves the volume if there are atmospheric gizmos specifiedor until the accumulated volume transparency falls below a certain cut-off threshold, or until a specified number of maximum steps is reached.
Note that this can be quite slow. Autodesk and Maya are registered trademarks or trademarks of Autodesk, Inc. For more information, see The Volumetric Caustics example below.

The atmospheric effect can also be confined with atmospheric gizmo helper objects. Exponential sampler — This sampler is used when there are no texture maps specified, in which case the volume properties are the same everywhere.
Lower values can be used for artistic effects. Density — controls the fog density. For example, compare the following two images, done with and without GI scattering. Use fog height — when this option is on and no atmospheric gizmos are specified, the fog is assumed to start from a certain Z-level height and continue downward indefinitely.
Offset V — allows you to adjust the refraction texture placement in vrwyenvironmentfog direction. Multiply by density and Add density to falloff. Multiply by density and Add density to falloff. The first algorithm is a simple exponential sampling scheme, which is used when there are no texture maps specified.
