The Displace operator allows you to displace particle mesh vertices using a texture map.
Texmap: the texture map used to displace particle mesh vertices.
Strength: the strength of the displacement, in local particle units.
Offset: the offset amount to apply to texmap values.
Displace open edges: controls whether vertices on open edges (edges that are not adjacent to two faces) will be displaced.
MatID filtering allows you to control which vertices in a shape mesh will be displaced.
Enable MatID Filter: controls whether material ID filtering will be enabled.
MatID: the material ID value that faces must have in order for their vertices to be displaced.
All adjacent faces must match: when enabled, every adjacent face to a vertex must have the matching material ID in order for the vertex to be displaced.
Some adjacent faces must match: when enabled, a vertex will be displaced if at least one of its adjacent faces has a matching material ID.
