I enjoy using Yeti over Xgen as a newbie in 3D grooming, but I don't know if hair created in Yeti can be imported into Marmoset like how Xgen hair can be converted to polygons. Or at the very least, can we use Yeti to make hair cards?
That sounds like a Maya settings issue: there must be some options for the resolution and profile / thickness of a curve inside Maya that dictate what the output to geometry looks like. If you set these values right - assuming you have access to them - then it should replicate the exact curvature/volume of the curve as it…
Ok, so I don't use Maya nor Yeti but if there's no obvious way to convert to polygons then surely you'll be able to instead convert the output from Yeti into curves/splines and to geometry from there? In my experience: forget about any conversion from hair system to hair cards - it'll get orientation of cards wrong most of…
