"what does this all mean?" There seems to be a problem with the network rendering using the rendercows after installing the Vue Infinite beta update, Pollee. When you install the update and launch the Rendercows for a render, they get updated. This update to the Rendercows seems to have a bug (on our systems at least) where Vue dosen't store the textures in the temp folder so the other computers on the network can get them. This causes un-textured blocks "Tiles" to appear in the final rendered image on the "Tiles" where the computers that could not get/find the textures they needed, rendered.
