Occlusion mesh processor

The occlusion mesh processor is a relative to the remeshing processor, but it generates the new geometry solely based on the silhouette of the input geometry. This means internal features and concavities will be filled.

The processor is designed in a way that will make the output mesh fall within the bounds of the silhouette of the original mesh at almost all times, making it useful for occlusion culling. Since it removes concavities it is not appropriate for shadow meshes that expect to self-shadow, but for pure casters it works very well. Due to the complexity of the task, this can be quite slow at higher settings.
