Foliage Materials & Start Culling

  1. Has anyone successfully gotten Start Culling in foliage to work?

I’ve setup the PerInstance Vertex node, into multiply with the foliage alpha- both into Opacity. Doesn’t seem to do anything.

  1. When viewing SpeedTree assets in the Asset Viewer they tend to have a ton of materials for each LOD, even when they aren’t drawing for that LOD. Is this a performance hit and how can I correct this without the SpeedTree modeler?

For the materials, make sure you are using the latest SpeedTree tools. Log in to your SpeedTree store account and download the latest version from the dashboard if you are not. One of the initial versions was not batching materials correctly when compiling the tree for UE4.
