Blend Shapes can blend between its inputs using average weights of each input’s respective channel. It interpolates point colors and/or texture co-ordinates between shapes.
Points or primitives in the first input to be blended.
Exaggerates blends between objects where values above 1 or less than 0 will result in over-scaled shapes.
Specifies which input to use when generating the cooked selection.
Enables blending of point positions.
Enables blending of point colors and alphas.
Enables blending of point normals.
Enables blending of texture coordinates.
Blend Voxel Data
Matching volumes will blend their data. This is not done by spatial position, but by absolute voxel index.
Shortest Path Transform Blending
Enables use of spherical linear interpolation to blend primitive transforms.
Point Id Attribute
If this attribute exists, it will be used to find corresponding points in the different blend shapes. For example, using id will allow particle systems to find matching points even if particles are deleted. If it does not exist or is blank, point numbers will be used for the matching.
Primitive Id Attribute
If this attribute exists, it will be used to find corresponding primitives in the different blend shapes. For example, using name will allow fluid systems to find matching volumes even if volumes are reordered. If it does not exist or is blank, primitive numbers will be used for the matching.
Assume Only Coordinate Changes In Input
This accelerates the blend speed when there exists an animated input that only has changing point positions. Unpredictable results will occur with this enabled if attributes or topology changes.
Assume Morph Network Setup
This accelerates the blend speed when the inputs have the particular wiring the Morph tool creates. The blend speed can be accelerated when the following three properties are true:
All of the inputs to the BlendShapes SOP after the first input are Edit SOPs.
The first input to the BlendShapes SOP is the same as the first input to all of the Edit SOPs.
If the Edit SOPs have a second input, they must all be the same.
Controls contribution of geometry inputs.
