Declaration

public void SetVertexBufferParams(int vertexCount, params VertexAttributeDescriptor[] attributes);

Declaration

public void SetVertexBufferParams(int vertexCount, NativeArray<VertexAttributeDescriptor> attributes);

Parameters

vertexCount The number of vertices in the Mesh.
attributes Layout of the vertex data: which attributes are present, their data types and so on.

Description

Sets the vertex buffer size and layout of the Mesh that Unity creates from the MeshData.

Use this function to set vertex buffer size and layout for newly created Mesh data (see Mesh.AllocateWritableMeshData). For details, see Mesh.SetVertexBufferParams.

After you have set the vertex buffer parameters, you can write the vertices into the array returned by Mesh.MeshData.GetVertexData. If you call this method on a read-only MeshData, Unity throws an exception.
