Merge Meshes Property Editor

Creates a new polygon mesh object by combining existing ones.

To apply: See Blending and Merging Polygon Meshes [Polygon Modeling].

To redisplay: Select the generated polygon mesh, click the Selection button on the Select panel, then click the Merge Meshes icon.

Inputs

Hide/Unhide	Hides all the inputs for the generated object to simplify the display of your scene in the 3D views, or unhides the inputs when you need to modify them.
Delete	Freezes the generator and deletes the inputs. This simplifies the scene once you are satisfied that you won't need to modify the inputs again.

Inputs' construction mode

Sets the connection point from which the operator reads to the top of the specified construction region of the input objects. For example, if this is set to Modeling, the operator reads the geometry and other attributes from the top of the inputs' Modeling region and ignores he effect of operators above it. If it is set to Secondary Shape (Result), it reads from the top of the inputs' entire stack, taking all operators into account.

Tolerance	The minimum distance between pairs of points on opposite boundary edges before they are merged or blended, in SOFTIMAGE units.
Blend	Draws edges between points that are within the specified tolerance. If this option is off, points within the specified tolerance are merged.

Merge Properties

All Properties and Clusters	Transfers all clusters from the input objects to the target object, even if they don't have any properties (like local materials, weight maps, vertex colors, etc.).
Materials, UVs, VertexColors, WeightMaps	Transfers clusters and cluster properties from the input objects to the target object. All cluster properties of the following types are transferred: materials, texture UVs, color at vertices maps, and property weight maps (but not envelope weights). Similar cluster properties on different objects are automatically merged if Softimage determines that it is safe to do so.
Shape Animation, Envelope Weights	Transfers envelope weights and shapes. Envelope clusters are always merged, but shape sources are not. Shape clips and weights are duplicated.
Normalize envelope weights upon transfer	Ensures that the envelope weights of each point in the merged object add up to 100. This gives good results in most cases. If you deliberately want to leave some points completely or partially unweighted, turn this option off.
Edit Transfer	Allow you to manually transfer, merge, and remove clusters and cluster properties. See Transferring Attributes Manually [Modeling and Deformation Basics].
