Interesting idea... there is currently no way to do this but it's interesting enough to warrant further thought. I've logged an issue here:
https://bitbucket.org/volumesoffun/cubi ... h-is-up-toHowever, you can probably force the mesh to be up do date (alomst) straightaway. If you search for 'maxNodeSyncsPerFrame' in the ColoredCubesVolume class then you should be able to increase the value here. If you set it to a big value then the whole mesh should be synchronized within one frame. This is fine for local changes but if you raise/lower the whole map then it will be too slow.
