I'm new to Blender, but I really wanted to take advantage of the sculpting. I exported a OBJ file from Maya, so I can sculpt more details on to the model. However, when I switch to sculpt mode, some areas don't smooth out. I'v tried smoothing, and decimating. I'm trying to avoid bouncing between Maya and Blender. I just can't figure out what I am doing wrong. I retopologized the model in Maya. Do I need to edit the polygons, or is it just an issue between Maya and Blender?
