Add – Adds mesh objects to the Objects list. The listed objects form the repeating pattern in accordance with the gizmo setup.

Remove – Removes selected meshes from the Objects list.

Remove all – Removes all meshes from the Objects list.

Crop box size X/Y/Z – Sets the gizmo size along X/Y/Z axis.

Fit in object space – Adjusts the size and position of the gizmo to fit all listed objects.

Height % – Sets the resulting VRayEnmesh height based on the Crop box size Z. 100% means using original crop box height.

Height offset % – Sets the VRayEnmesh geometry offset along the surface normals based on the Crop box Z size.

Use mesh UVW mapping – When enabled, uses the mapping of the listed objects for shading the result VRayEnmesh. This option is disabled by default and the mapping of the original base mesh object is used for shading. See the Use mesh UVW mapping example below.

Use mesh IDs – When enabled (default), shades the VRayEnmesh using the polygon materialIDs of the objects that form the pattern. This comes handy with shading setups that include VRayMultiSubTex or Multi/Sub-Object material. If disabled, the polygon materialIDs of the base mesh object are used. See the Use Mesh IDs example below.

You are able to use VRayMultiSubTex and VRayUVWRandomizer for texture variations on a single pattern level of VRayEnmesh with the help of the By Instance ID randomization mode.

Map channel – Specifies the mapping channel of the base surface to use for pattern tiling.

Tiling U/V – Sets a tiling factor for the pattern. For more information, see the VRayEnmeshMod Tiling example below.

Offset U/V – Sets a pattern offset along the base surface local mapping.

Rotation – Sets pattern rotation around the base surface normal.

Random offset U/V – Sets a random offset along the base surface mapping to every pattern in its tile.

Use rotation steps – When enabled, the random rotation is snapped to distinct angles as formed by using the Random rotation value as steps count to cover the full 360 spectrum. For example, if Random rotation is set to 4, the pattern mesh is randomly rotated on a 90 degrees step (360/4) - 0, 90, 180, 270, 360 (0). If there is also a Rotation set, for example to 30 degrees, there is a 30 degrees offset - 30, 120, 210, 300, 390 (30).

Random rotation – Sets random rotation up to the given angle to each pattern around the base surface normal. Rotation happens in positive and negative direction.

Step counts – Sets rotation steps count when Use random rotation steps is enabled.

The VRayEnmesh gizmo box is set in such a way that its edges are in the center of the tori's periphery. Thus, the tori tile seamlessly.

Example: Use mesh UVW mapping

 

This example shows the effect of the Use mesh UVW mapping parameter. Keep in mind that the geometry used for pattern has its own correct mapping so that textures are placed and tiled properly on that single geometry. The VRayEnmesh option simply controls whether to use the mapping from the pattern or from the base object.

  • Currently, VRayEnmeshMod is supported on V-Ray CPU, Chaos Cloud Rendering, and V-Ray Standalone.
  • VRayEnmesh is incompatible with render-time created geometry like displacement and V-Ray Fur.
