Looks very promising indeed. Like Uvhausen, I also need to be able to sculpt and modify static mesh on a very detailed level. Typically I have been using Meshmixer for this as I love some of the features of that software. Their tools are great. I love that you can create a spline (although you can only paint the a shape and then tell it to use the border as the spline instead of being able to just draw in a spline manually), tons of sculpting options and even things such as adaptive remesh, which is fantastic at keeping your final tweaked mesh very optimized.
I think you guys are only scratching the surface here on this. If you made is so we could use draw splines on the static meshes in addition to powerful sculpt and mesh optimizing tools, wow, that would be fantastic.
