Cheers Arran,

I'll hopefully have an update tonight, gonna try and get the island sorted first then onto the trees.

I still need to plan how I'm going to create the trees. What i've thought about so far is to model and texture a few types of Jungle plants and forna then assign them to particles as instances, then have the island surface emmit the particles in a random order to build the jungle (with a bit of tweeking and/or MEL to get some variation), then use maya hair connected to geometry for roots/vines etc.

Not sure if it will work as i've never tried anything like it.

Also formulating a reason of how a chunk of the jungle ended up floating on huge balloons!!
