We learned how to paint a customised bump map from a texture image in Photoshop.

Firstly, I created a black and white adjustment layer. And then I put up the contrast and blurred it. Next, I cleaned some grey noise with Dodge Tool. It basically just make the area you painted overexposed.

In Mudbox, I created a plane and imported the bump map I just painted in Photoshop from Add Stencil button. When I double click on the stencil I imported, I could start to sculpt it from the bump stencil.

Next, I imported the diffuse map to paint the colour with Paint Brush Tool.

We also used the bump map which was painted in Photoshop to make the brick wall in Maya.
