Have been having problems since I downloaded Skatter for SketchUp!! The programme does not work smoothly and can only create small grass patches but nothing more!! and very far from being able to generate unlimited vegetation as advertised! if SketchUp is not finding a solution then Skatter should because it is a complete useless piece of software in the way it works now!.
Please help if you know what the solution is!! oh this has not improved in the latest SketchUp 2017!! 
Could you elaborate on the issue?
What happens exactly, any error? Or is it just slow?
Are you using Vray 2.0 by any chance?
