          Meta=(DeprecatedFunction, DeprecationMessage="This function is deprecated for Blueprints because it uses the unsupported 'Color' type. Use new 'Update Mesh Section' function which uses LinearColor instead.", DisplayName="Update Mesh Section FColor", AutoCreateRefTerm="Normals,UV0,VertexColors,Tangents"))
void UpdateMeshSection

Remarks

Updates a section of this procedural mesh component. This is faster than CreateMeshSection, but does not let you change topology. Collision info is also updated. This function is deprecated for Blueprints because it uses the unsupported 'Color' type. Use new 'Create Mesh Section' function which uses LinearColor instead.

Parameters

Parameter

Description

Vertices

Vertex buffer of all vertex positions to use for this mesh section.

Normals

Optional array of normal vectors for each vertex. If supplied, must be same length as Vertices array.

UV0

Optional array of texture co-ordinates for each vertex. If supplied, must be same length as Vertices array.

VertexColors

Optional array of colors for each vertex. If supplied, must be same length as Vertices array.

Tangents

Optional array of tangent vector for each vertex. If supplied, must be same length as Vertices array.
