How do I split up geometry without any gaps? I'm trying to better organize my scene and I'd like to split up my geometry into some parts. However, there always remains a gap in between the parts and I don't get why. Of course, I can easily join the separate objects together into a single object and render the object as a whole:






Can it be that it is simply not possible to keep components of meshes separate? I can not find a way to do that properly but I'm sure there is a way. What am I do wrong?
Make sure you disable any Smooth modifier on your objects. It will effectively &quot;shrink&quot; the borders of the mesh, creating gaps in disconnected islands.
