Automatic Model Texturing
Lets face it very few people enjoy unwrapping UVs. Often its a necessary and tedious task in a full modeling workflow. Without quality UVs is can be difficult to achieve any sort of accuracy in the textures.
That being said sometimes we dont need accuracy we simply need to apply a good texture to a whole model for a quick render. Here you are in luck!
Using the Blended Box mapping feature of texture nodes in your Cycles shader setup allows very fast texturing for many objects. This makes it very easy to texture everything from metal to concrete to dirt. Its a great technique that can really speed up your workflow.
One thing to keep in mind though is that it only works within Cycles and so does not work for exported objects (at least not until Cycles has baking).
