One of the problems I've run into importing my A:M models into Blender is that most of my models have very limited geometry. I can add a subdivision modifier, which does smooth out the parts and pieces, but it also reduces them in size, so I end up with a model that no longer looks like it did in A:M. Today, I watched this youtube video...
A subdivision modifier that keeps the model's volume!
And suddenly, an old friend appeared, looking not a day older (or skinnier!)
I'm busy with the latest Stalled Trek, so I can't really go off on a deep dive right now, but if you've run into this problem, this appears to be a solution!
