Note that Voxel Play will generate chunks according to the camera frustum (if "Only Render In Frustum" option is used) and respecting the "Force Chunk Distance" and "Visible Chunk Distance".
You can also ensure chunks around certain objects are generated on the server by attaching the Voxel Play Behaviour to the object and set the "Chunk Area" to certain extents, like (2,1,2) and click "Render Chinks" - that will ensure the chunks are generated on the server as well regardless of the camera.
