Im totally a noob in sculpting with Blender, I want to use some alpha brushes to sculpt hard surfaces, I add a texture as a brush, select the texture under the sculpting brush, but when I use it it´s rounded and soften towards the corners (see picture). This happen to me with every texture I try.
How can I make my brush harder and avoid this softnes? Thank in advance to anyone who can help me out with this.
