Works pretty darn well as a bark texture on an actual tree object. Here is a "Fir Tree" iteration clip file. I have also gone through and named all the shaders for study and a base for other iterations people or I may come up with.
The tree is a Douglas Fir or Blue Spruce depending on foliage textures, and done by AP. Really well done objects.
Edit: Unsure why the midsection post image got so low quality. It was saved in max quality in PS and looks fine on my HDD.
