Method UpdateTriangles

Source/Engine/Graphics/Models/MeshBase.cs:26–37

Updates the model mesh index buffer data. Can be used only for virtual assets (see and ). Mesh data will be cached and uploaded to the GPU with a delay. The mesh index buffer (triangles). Uses 32-bit stride buffer. Cannot be null.
