I drew a bushy manface in Tilt Brush on the HTC Vive, and realized that they had added a way to actually export the drawing into a 3D file!
So I used the python script that Tilt Brush comes with to export it into an OBJ file. And after punching my head through a wall to figure out how you run python scripts, I finally got an OBJ file out of it. I then took this OBJ into Maya and rendered it with my production renderer, V-Ray.
The results were quite nice!
I didn't get the textures and alphas of the brush strokes, so you end up with long flat planes that represent the strokes.
