Hi silverblade33. The only reason I havent/cant do that is because I have pretty much maxed my computer resources. The scene stands now at 1.6 billion polygons and another terrain crashes my machine. I have tried a few times and though I have created a scene (Southern Migration) with significantly more Polly's (around 4 billion), some scenes dont like/allow you to add to them I assume it has to do with the type of objects being used. I thank you for the suggestion though:) To wabe, I created my terrain the usual way, then exported the terrain out as a .jpg file. Opened it in Photoshop and the aria for the river was made white, and the other parts of the terrain were made black. Back in Vue, I created a mixed material (parametric) and used the map I made in Photoshop to drive/separate the materials. Thanks... Gareth:)
