Thanks Wabe and Nanotyrannus. I've got a demo copy of Vue4 Pro and was trying it out last night. I'm really keen on the terrain editor which works in 3D. This is much more intuitive than the 2D version in Vue3. I just can't visualise this properly when I'm trying to sculpt terrains. This feature is in the standard version of Vue4 and is what appeals to me most at the moment. Kevin
