Cinema 4D - How to scatter Forester assets with Redshift

Forester is a great tool for adding foliage to your 3D scenes in cinema 4D but it can quickly slow down your scene file when you're using the multicloner object for scattering.
When you're rendering in redshift you can use the redshift matrix scatter with effectors to achieve the same results as the multicloner while maintaining a very speedy viewport and render times.
Collect the forester objects you'd like to scatter under one null labeled instances, select the object tag on the redshift matrix object and add the forester objects as custom particles by clicking the picker icon and selecting each object.
Select the matrix object and click the object tab. Change the mode parameter to Object. Drop the geometry you'd like to scatter your foliage on into the object window. Adjust the count number to what you think will be appropriate. Turn on the Redshift Renderview to preview the scatter. Your objects will probably have the incorrect alignment so select the Transform tab of the Matrix Object and rotate them -90 degrees under the pitch parameter.
Now add a plain effector to the scene, under the parameter tab turn off the position and rotation. Under scale select the uniform scale check box and change the scale value to -1. You can add a random effector to the matrix to randomize the scale and rotation of your scattered particles.
This will scale all the matrix particles to 0. Now you can add fields under the falloff tab to art direct which areas of your geometry will populate with particles. I'm using a high poly terrain object so I'll stick with standard field objects but if you were using a more low poly geometry you could also use a vertex map as your field falloff.
That was a quick intro to using the redshift matrix scatter to incorporate a large number of forester assets into a scene without slowing it down.
