Setting up Damage Types for the Foliage Plugin

If you haven’t setup the Foliage Plugin yet, follow this tutorial first.

Create a new Blueprint Class based on the DamageType

Set the new Damage Type required in your Foliage DataTable

When Applying damage to your Foliage, specify the new Damage Type

All done, if the incorrect damage type is applied, you will not be able to interact with the Foliage

Setting up Destructible Meshes with the Foliage Plugin

If you haven’t setup the Foliage Plugin yet, follow this tutorial first.

Create a Destructible Mesh of your Foliage Mesh

Example Settings of a Destructible Mesh (a rock in this example)

Add the Destructible Mesh to the Foliage DataTable you created in the previous tutorial

Important here is that the IDs (marked in RED) are the SAME, it doesn’t matter if the Destructible Mesh is Empty (if you don’t have one for a different mesh)

Another Example

Add a Destructible Component to your BP_FoliageActor that you created in the previous tutorial

All done, the Foliage Plugin will handle dealing damage and visibility of the Destructible Mesh
