2: Smoothing Shapes and Adding Materials
Today, I explored how to smooth out my shape and add different materials to each part using geometry nodes.
Process
I wanted my combined shape to have smoother edges, so I used the Shade Smooth node at the end of my node tree. However, this smoothed all the edges, including some that I wanted to keep sharp.
To fix this, I applied the Smooth by Angle modifier (a feature in Blender 4.1). This allowed me to control which edges were smoothed based on their angles, preserving the sharp edges where needed.
Next, I wanted to give each part of my shape a different color. I added the Set Material node before the Join Geometry node on each shape. This let me assign a unique material to the cylinder and the cone individually.
Now, I have a single complex shape with different materials and some sharp angles, giving it a more defined and visually appealing look.
Nodes Used and Their Functions
- Shade Smooth: Smooths shading across the surface of the mesh.
- Smooth by Angle: Controls smoothing based on the angle between faces.
- Set Material: Assigns a material to the geometry.
