Sample Mesh Index

Menu Path : Operator > Sampling > Sample Mesh Index

Menu Path : Operator > Sampling > Sample Skinned Mesh Renderer Index

The Sample Mesh or Skinned Mesh Renderer Index Operator allows you to fetch index buffer data of geometry. Both UInt16 and UInt32 format are supported the output of this operator is always an UInt.

Operator settings

Property	Type	Description
Source	Enum	Choose the kind of geometry to sample, either a Mesh or a Skinned Mesh Renderer

Operator properties

Input	Type	Description
Mesh	Mesh	The source mesh asset to sample. This property only appears if you set Source to Mesh
Skinned Mesh Renderer	Skinned Mesh Renderer	The source Skinned Mesh Renderer component to sample. This is a reference to a component within the scene. To assign a Skinned Mesh Renderer to this port, create a Skinned Mesh Renderer property in the Blackboard and expose it. This property only appears if you set Source to Skinned Mesh Renderer
Index	Uint	The index offset to sample the current index buffer.

Output	Type	Description
Index	UInt	The sampled index, or zero if input Index is out of bounds.

Limitations

The Mesh index sampling feature has the following limitations:

• If a Mesh is not readable, the Position (Mesh) Block and Sample Mesh Index Operator return zeros values when they attempt to sample it. For information on how to make a Mesh readable, see Model import settings
