Here are the first set of images I put together while taking Jama Jurabaev's Unreal for Artist's course. Some BMS assets, some Gravity Sketch vines, a light dusting of Blender, but the majority of it was made in Unreal, whose modeling tools are surprisingly good. I was able to get much further than I thought without leaving the program.
Oh, and lots of sand, which gets everywhere...
I had a great time making these. Jama is a fantastic instructor, incredibly helpful and patient. Highly recommend the class if you're looking at breaking the seal on Unreal.
