Easy tutorial on Using Alpha Brushes in Blender 3D


Please pause where necessary. This is what you get when you open Blender. Tapping “A” will select everything. Tap “X” and click “Delete” to delete everything. Shift+A to open create menu and add a new cube. This has only 6 Faces. Let’s sculpt this and add more detail. We can either subdivide it or let blender add mesh detail dynamically where necessary. Let’s let blender add mesh detail dynamically. Go into Sculpt mode. Lets try blender’s dynamic topology which will add high poly detail where ever needed on the go. Scroll Down to Dyntopo and enable it. Detail Size is the resolution of the edges that are created blender’s dynamic topology. Lower the value sharper the edges. Enable smooth shading for newly created topology. Go into options and enable Fast Navigate. This helps in smooth navigation for high poly models. Reduce the Detail Size for sharper edges. By default symmetry is enable for x-axis. Lets Disable this for now. Add some major details. Dyntopo has errors. You can see them at the edges of the cube. Adding random details Smooth them out You can see the newly created topology and where we have not added any details the cube is still low poly. Choose sculpt draw brush again Add a new texture Renaming it to “Details” Go to texture tab in properties and select textures Make sure the new texture is selected. Open a new image There are some freely available alpha brushes made for Zbrush. I’ll put a link in the description. Select one of these. Adjust the strength and radius Click to add the detail Enable Matcap material This is low res as visible Decrese the detail size for sharper topology Quality is still not up to par. Decrease the detail further and you can see the quality of the newly generated topology increases Lets change the brush This is fairly high quality Notice the rapid increase in the faces at the top bar and the viewport has started to lag as well. Clearly my systems hardware isn’t able to handle it. Make sure to enable smooth shading Lets try another brush Alpha brushes are a very effective way of adding minute detail that is otherwise very time consuming to model.
