Crate Final Renders
Here's the final bake and textured version of my crates. To get a cleaner bake I actually went back and adjusted the models just a bit.
For the textures I actually used quite a few gradients to get the specific color I wanted for the wood. Making the crate darker at the edges and bottom, and lighter in the middle.
