What do you guys think about MakeHuman?
As in, do you consider it lazy or unethical to use?
It's a tool.
Ethics and laziness really depend on what you're doing. If you're making a game as the artist and use makehuman for all of your characters without doing anything to them then yeah, that's lazy, if you don't acknowledge that you used makehuman to make them then that's unethical.
If you're using make human to set up a scene with different kinds of people and then go in and pose them, dynamesh and sculpt over them and all that jazz then all you have is a basemesh generator, not unethical just recognize that it's not all your work.
