//---- Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
|

// Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
|
||||
// Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
