My current 3D graphics setup revolves around Blender, ZBrush and, less often, Marmoset Toolbag 3. Transferring the meshes between ZBrush and Blender is the constant dance of exporting and importing (yes, I know about GoB but it’s not good enough for me). I strongly dislike this back and forth. I feel it adds a lot of friction, throws me off and wastes a lot of time. That makes me experiment with inter process communication. This is one of those experiments.
