Description

Format of the mesh index buffer data.

Index buffer can either be 16 bit (supports up to 65536 vertices in a mesh), or 32 bit (supports up to 4 billion vertices). Default index format is 16 bit, since that takes less memory and bandwidth.

Note that GPU support for 32 bit indices is not guaranteed on all platforms; for example Android devices with Mali-400 GPU do not support them. When using 32 bit indices on such a platform, a warning message will be logged and mesh will not render.

Changing indexFormat sets subMeshCount to one and clears the index buffer.

Refer to Mesh.MeshData.GetIndexData for an example.
