there was a plugin by chris3d (i think, there are two chris' w/similar names so im not sure i said the right one) that you can use more effiecient stencils that i believe even work with open mesh's. although im not sure if its been broken by any of the updates to the engine since it was released. probably not even worth the search effort if your going to use shadec anyways, but figured i'd offer up the info anyways.
