This page offers information about V-Ray Enmesh in Maya.

Overview

Enmesh is a tool that uses geometry as a texture to “coat” objects. It can tile and repeat geometry infinitely, bend it over a desired surface or cut it according to the surface’s limits. It can randomize rotation and offset to produce non repeating geometric patterns.

Enmesh can be used to create patterned fabrics, woven and knitted materials as well as chain mail. It can also be used to scatter grass, pebble patches, stone tiles and many more.

Enmesh can use multiple meshes as reference to "coat" the source mesh's surface. However it can be assigned to only one source mesh. The source object's material is applied to the geometric pattern, and the mesh's UVs determine the tiling.

V-Ray Enmesh works similarly to a texture, so UVs and their scale and tiling should be used accordingly to achieve the desired effect.

V-Ray Еnmesh is currently available only for CPU rendering.

Basic Parameters

Reference Objects – Shows the set containing the objects used as reference meshes.

Source Mesh – Shows the set containing the mesh used as a source.

Force Invisible Source – When enabled, the Source Mesh is invisible.

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

Height % – Sets the VRayEnmesh height based on the Crop Box Size Y value. 100% means it uses original crop box height.

Height Offset % – Sets the VRayEnmesh geometry offset along the surface normals based on the Crop Box Y size.

Fit in Object Space – Clicking on this option positions the Enmesh gizmo in the viewport exactly around the reference object.

Use Mesh UVW Mapping – Uses the source mesh UVW for shading instead of the Surface UVW. This option is disabled by default.

Use Proxy Mesh IDs – Uses Proxy Mesh IDs for shading the patterned surface if a VRayMultiSubTex or MultiSubObject are used.

Tiling Options

Tiling U/V – Sets a pattern tiling in UVW space. Use these parameters according to your UVs size.

Offset U/V – Sets a pattern offset in UVW space.

Random Offset U/V – Uses the static UVW offset as base and adds it when calculating the randomization effect.

Rotation – Sets a pattern rotation in UVW space.

Use Random Rotation Steps – Makes Random Rotation parameter be based on 360/X, where X is steps count. For example, if Random Rotation is set to 4, the pattern mesh is randomly rotated on a 90 degrees step (360/4) with a 30 degrees offset - 30, 120, 210, 300, 390 (30).

Map Channel – Uses the set map channel for the surface geometry.

Example: Multiple Reference Geometries

This example shows how applying multiple reference objects affects the mesh. Click on the expandable field to see the original reference geometries and the order they were used in. A V-Ray Light material with varying Opacity is applied to the reference objects.
