Well turned a winter fir in to an Xmas tree. Yes the bulbs are in the branches not on the branches. Two possible solutions, both would double the polly count. Ether I can duplicate the tree, put the bulbs on the duplicate, then move it down a bit and make invisible. Or add thickness to the branches. I think carrara has on going issues with single side meshes, and that is what is causing issues with the surface replicator. One is a sure cure.
