Hmmm, that is odd Lordstormdragon. I already had Java installed because I needed it to run "Arbaro", another Java-based tree making app which is quite good. Can you tell I'm nuts about trees,lol? I downloaded the zip to my documents, unzipped it it with no probs, dbl. clicked on the file called "povtree.jar" and the app opened with a nicely designed and easy to use graphic interface. I clicked on a preset and tweaked it a little and from there exporting was a doddle. I have found that sometimes I need to add ".inc" to the model name so that the POV-to-.obj conversion proggie will recognise it.
