Foliage not texturing in Standalone

Hi,

A landscaper I am working with has using an instanced foliage actor. It looks fine in the editor and new editor window but the Foliage is not texturing in Standalone.

Any ideas why this might happen? I mainly work on the programming side of things so I’m not sure why this would occur.

Here is a screenshot of what is happening. http://i.imgur.com/kFcx9zN.png

Any ideas?

Kind Regards
