# Can anyone help me understand the difference in shading on these 2 models?

Can anyone help me understand the difference in shading on these 2 models and how I can get the rough one smooth like the smooth one? It's not just shading flat or smooth.

If you want to have the right bush look like the left one then add a Normal Edit modifier. Use type Radial (default) with Mix Mode set to Copy (default) and a Mix > Mix Factor of 0.950. In Object Data Properties > Normals the Auto Smooth checkbox must be enabled.
