AllocateUIMesh(ExtraVertexChannels, int, int, UIMesh)

public void AllocateUIMesh(ExtraVertexChannels channels, int vertexCount, int indexCount, out UIMesh mesh)

Parameters

channels

ExtraVertexChannels

vertexCount

int

indexCount

int

mesh

UIMesh

Remarks

Channels not requested return as empty slices on the resulting UIMesh. Use the result as input to DrawData.SetMesh for tessellation refinement or wholesale geometry replacement. Memory is valid for the duration of this callback and any jobs added via MeshModificationContext.AddMeshModificationJob.
Requested channels that are NOT enabled on the panel's ExtraVertexChannels mask are dropped and the resulting 
UIMesh
returns empty slices for those channels. Check slice lengths before filling.
