Fair point on the cargo truck. I think maybe somewhere between the very square first one and the rounded second one. I'll try to play around a bit more with making it industrial, then try to make it a bit more futuristic.
I also like the idea of details on the cargo bed for the dump mechanics. Maybe some sort of track, or knuckles for the arms, or maybe giant sockets...Sliding bottom doors are also a possibility, much like a grain wagon with the funnel-type bottom. Though as you said, that would necessitate animations for all the cargo types.
Nothing new to post at the moment. I was working on a spider model, but I was stupid and didn't save for a while. So of course Murphy paid me a visit and I lost quite a bit of work. I'm hoping to get more time this week to work on it, but might not be till the weekend now.
Cheers
