The VRayEnmesh modifier generates a render time patterned geometry over a mesh surface. The modifier can be used to create crochet fabric, chain mail, nets, and anything that requires inflex geometry tiling.

Multiple objects can be included in the modifier's Objects list to form a complex pattern sample and tile together over the mesh surface.

The modifier's gizmo encloses the sample to be tiled. You can adjust it to fit all the listed geometry or crop it conveniently by modifying the size and position of the gizmo. Therefore, the gizmo is also referred as crop box.

The VRayEnemsh UI is slightly different in 3ds Max 2018 due to limitations in the Qt embedded version.

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 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.

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

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.Rotation – Sets pattern rotation around the base surface normal.

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 random rotation stepsWhen 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. When

Step countsSets rotation steps count when Use random rotation steps is enabled, the value of Random rotation is considered as rotation steps count instead.Map channel – Specifies the mapping channel of the base surface to use for pattern tilingrotation steps is enabled.
