well I have a modular christmas tree in a set I just sent in the other day for testing. One of three sets really. Its mmm .. medium distance realistic? suitable for room renders. I wouldnt suggest for macro style closeups, and its not passing for a natural tree. Certainly not in the 9 rainbow coloirs I provided *lol*

Traveler at RDNA did a BigBranch freebie recently, suitable for those ornament closeups. And then of course theres the pricey but lovely xfrog pine trees
