I'm currently building a RC paving library for an urban landscape design project and have run into the following issue; sometimes an RC object goes partly missing during rendering. As far as I can tell it's happend to a couple of the objects present which have a running bond layout. Below some quick tests with selections. Have you guys run into this before? The landscape project will run anywhere from a year to 10 years because of the scope so I want to have a good base to keep me going for awhile without having to redo large portions of the project anytime soon.
RC Objects are pretty simple, simple box for tiles and I've used the different files you have posted on the forum as a base to build the layouts (stack, running, herringbone). You can ignore the manholes in the images, they are separate geo placed on top.
