Vegetation Studio and Pro Support
By default the system supports Vegetation Studio Pro right out of the box. Installing VSP will override the usage of the Unity terrain system and prevent the Unity terrain from functioning if it was set up prior to installing VSP. If this is the case, simply configure the VSP settings the same as the terrain was set up prior.
For multiplayer support a few steps are required. Once you have configured your VS/VSP setup to your liking, find the collider system that is attached and click, Bake Colliders to Scene.
Delete this entire gameobject and start the process again anytime you make a change on the colliders, trees or large objects in your scene. You can click this without causing an issue.
This will create a new gameobject in your scene like this. Select this gameobject and click on Add Component. Add the Harvestable Mask script to this object and once it has loaded, click the Rename Colliders. Click Server Only on Network Identity as only the server needs this object.
Clicking Rename Colliders will properly name the object so can identify the collider and disable it server side to prevent the raycast from hitting this object.
