Leaf material missing in the rendered image

SketchUp version : 2017
Skatter version*1.4.10
Vray version: 4.00.01
OS : Win10
This happens when choosing Trees01 and /or Bushes01 from the Skatter Library (“Proxies” and “Render Only” Checked). After I render, the render is missing the leaf material. This happens every single time, even in an empty new skp file. No errors are displayed.

This has been fixed in V-Ray 4.00.02, also known as V-Ray Next for SketchUp, hotfix 1
