Hi, so I just did a small test and it appears that sub-objects are not supported at this time. You would need to merge the mesh into one using connect objects + delete and then copy all the tags from the original mesh to the proxy. Note, that after doing this your mesh may look grey but it should render okay. I hope that helps.
Hey, thanks for your reply!
Yep, I really did not expect it to be necessary to copy the tags from one scene to the other. Pretty much underdeveloped feature this whole proxy at the moment...
In such a state, what big sense do Corona proxies make?
Also that it doesn't support the sub-objects... bad.
Better to not even imply such a feature if it is so rudimentary in its abilities.
Corona dev. team can do better!
