STEP 6: From the flat colour layer I select various sections to be brought into the main scene. Here I have selected the window frames.

STEP 7: I can then change the colour, pattern or shading of individual elements. I often colour sections in very contrasting colours in SU so that they can easily be selected and modified in Photoshop.

STEP 8: Glass effects are easily produced using Gradients. Here I have used a default style and then changed the colour to Blue.
