The addon helps you to project ready-made micro objects onto your target object quickly and easily. Of course you can change them or create and use your own micro meshes. The scaling and phase can be adjusted quickly and it helps you to visualize the density quickly.
There are of course limitations that cannot be fully utilized, but for a correct creation of micro meshes I recommend the Blender internal addon (Tissue) This allows you to project your micro mesh perfectly onto your target object, which is better for accuracy. With Simply Micro Mesh it is easy to create a concept and work with it already if you want.
This Addon includes more than 120 ready-made Micro Mesh presets to use!
