Check out a new add-on for Blender that will ease up the scattering workflow in it. 

A new add-on for Blender will help you with scattering and will boost your productivity and creativity with its new features. Here are some of them: 

• New UI simplifies the production process by keeping everything in one place, so you don't have to go back and forth in editors.
• The add-on is heavily automated. Do the work that could take hours with a few clicks only. 
• The particle system in Blender is much easier with Scatter. Creating it isn't long and boring anymore. It takes 4 clicks only to manage it. Scatter fixes the particle count in Blender, so you can choose the density per/m²/km². It also secures your computer from freezing when working with the particle system.
• With Biome Management System, you can create a photoreal biome real fast. 
• You can tweak anything you need in no time.
• Included «Bezier-Boolean» toolset will help you create paths following bezier-curves easily. 

There are also Scatter Tutorials that can help you understand how to install the add-on, learn basic steps of scattering and how to work with the biomes and parameters. Check the videos here. 

You can purchase the add-on on Gumroad.
