Is there a tutorial for shading as I would love to know how to do it properly
There is one, we call it the 45 degree shading rule:
The 45 degrees shading rule is quite simple. Everything that is more horizontal then vertical gets shaded. So, where the hull is vertical (90 degrees angle with the waterline), it is unshaded, where it is horizontal (0 degrees with the waterline) it is shaded. The edge of the shaded area is exactly in between: 45 degrees with the waterline.
- Shade lighter the parts facing up (for example ducted propellers or torpedo belts). Here count the same rules, just facing the other way.
- Overhang shade under overhangs, even under water. (This is just the standard sb overhang shading, and I only use this when it is not clear otherwise there is an overhang. This is mostly the
case in the stern when a skeg is used. It is NOT usable for shading under bilge keels)
- Above the waterline shading. It is best to stay consistent in the shading style from keel to main deck, as these parts run over into each other fluently.
