bClearTrianglesPerFrame

bool bClearTrianglesPerFrame

Should we auto clear section triangle allocations per frame or not.

bHasColors

bool bHasColors

Allocates space for vertex colors when enabled.

bHasTangentBasis

bool bHasTangentBasis

Allocates space for tangent basis when enabled.

Materials

TArray<FNiagaraDynamicMeshMaterial> Materials

List of materials to use.

NumTexCoords

int NumTexCoords

Allocates space for the number of texture coordinates requested.

NumVertices

int NumVertices

Allocates space for the number of vertices we will use, leave as zero if you intend to allocate dynamically via VM calls.

Sections

TArray<FNiagaraDynamicMeshSection> Sections

Sections to render, each section will generally result in a draw call. Triangles are contiguous between sections, i.e. Section[1] triangles will begin after Section[0].NumTriangles.
