I've been playing around with this for weeks in spare time. Finally got the outside form of the crankcase to look decent. There are still some "funnies" but I'm letting them go for the moment.
It's still incomplete, and I need to develop a much better "steel" appearance in Keyshot for the propshaft etc, and the filler cap, particularly.... But it's a start
A bit of improvement. I like the steel better, although it still is too perfect... I wanted it blotchier , but not a LOT blotchier. Also duller, less specular reflection.
added details, have not worked on the steel material, although it is growing on me, just as long as I could dull it a bit
