Ok here is a bit of a solution; if you have Hex, open the .obj in Hex, cut the leaves out and delete them by the shader domain. Then use the surface replicator to put new leaves on the vines.

I found a suposed 2012 version, but it works no better.

It's not the png textures I replaced them and found the leaves aren't actually UVmapped, or mapped in a way carrara can read it.
