Unfortunately, I haven't had time to try out the Pre-Release Phase II this week (too much work to do at university
But I finally handed in my bachelor thesis last week, yay!!
), but I will chime in later as soon as I've tried it.
About that texturing issue: If you look closely at the supplied tries you will notice that these aren't seamless, either. My guess is that there's simply no way to make textures blend entirely without manually editing the UVs in third party software like e.g. Bodypaint 3D. But that's just an estimation. Either way, you can always play around with the different mapping modes in the material editor. For non Vue-users here's a short explanation:
World mapping modes: Think of your object (the tree) as a "window" to the material that is stretched and repeated infinitely across the entire world space. If you move the tree, you will see another part of the material.
Object mapping modes: The material's position is attached to the object. Moving the tree won't change the pattern on the object.
Parametric and standard: When you resize an object with parametric mapping, the material will resize accordingly, too. For example, if you make your tree three times bigger in scaling, the material will also be scaled up three times in its size in order to keep the correct relation of sizes with the object. If the object has standard mapping applied to it, though, resizing the object will reveal "more" of the material and the material itself will stay the same size.
Also, if you double-click on the material preview (the sphere), the content browser will pop up. You can find procedural bark materials that are fully adjustable under Plants=>Barks.
