Hi Guys. I was going to post these in the WIP thread, but saw KungFuSquirrel's comment about keeping things together. I will definitely be doing a lot more texturing in the future, but for now, here are my first attempts at hand-painting stuff, all of which was learned from PhillipK's excellent tutorials. They were designed with UDK in mind, so I wanted to keep them quite clean, since a lot of the details would be added by shaders. Feedback is as always appreciated

This is the orange brick with shaders in the UDK viewport:

A yellow variant of the same brick:

With the paint effects which can be drawn on the texture:

I then used the same handpainting technique for some concrete to see if it worked.

How they might look together.
