Sascha you are amazing! Thank you so much for this. I got into SDF modeling because of you and I love it so much! I've only done a little bit with it so far, but every time I open SDF Modeler I'm just encouraged to create more.
The way I use it currently is to start in SDF, then export, import to Blender and manually retopologize, then sculpt from there. It's a bit tedious, but I really like using sdf like clay to make a base mesh for sculpting.
