I know this question had already been asked.
But that didn't help.
It's my first blender model, but i already sculpted the body, boots, gloves and other stuff without problems.
After switching to sculpt mode it looks like this, with a multi-res of 2 However, if i try to sculpt it, no matter what brush, nothing happens. Even with strength at 1.0 using the flatten tool, or using the Mask tool.
Applying a solodify didn't help. Neither did deleting the multi res, duplicating the mesh and reapplying the multi-res. Nor using subdivision first and then a multi-res.
I tried using Alt+C "Mesh from Curve/..." and still no success with sculpting.
After enableing dynotopo and trying to sculpt, a switch back to edit-mode showed new vertices. But no changes to the actual 3D form in Sculpt/obejct/edit mode. Only new vertices.
I always tried both my wacom tablet and my mouse.
I can still sculpt the character, boots and other stuff (hidden, but listed in the outliner) in the same Scene. These are created from a cube and not planes though.
What am I doing wrong? It should be possible to sculpt from a plane, I looked it up in tutorials and such.
