Guns Crate model

[Acies]

When using crazybump set the shape recognition slider to 0 (otherwise things which are straight may come out looking bent - which can be useful when making certain organic things). To hide a text, simply export a diffuse without the text layer and import that into crazybump. Then generate your normal map.

Edit: As for the model I'd do what hirnwibel said. I'd also tone down the spec map.
