As said on the discord. Show us those attempts, tell us what you are doing to get the shading and we can help you out. Nobody will do the work for you (except I actually already did that for you because you had trouble, while explaining the entire process while doing so)
You didn't like the result using the 45 degree rule, so you requested someone to do it for you using a different shading rule. I recommended using 90 degree rule (which was closest to the kind of shading you showed in images what you wished for) but that you should try to apply that yourself, and post the progress so people could help out if you got stuck.
You spend the next posts on the discord how you needed to be a mathematician to do hull shading and it was too complex for you and that someone else should do the work for you.
But you've worn me down.
Here you go, perfect shading for both the hull and propeller shaft and boats according to the zero degree shading rule. Anything not visible from the side is shaded or highlighted.
If you don't like that, show some effort trying yourself so people can help you improve. People on shipbucket are eager to help create great work, but they will not do the work for you.
