I'm trying to scatter a set of objects over a vertical surface using UV surface mode. This particular scatter has to do some specific things though. The density of all objects need to fade from one side to the other (left to right). As well as this the i need to scatter the different geometry object types from the base to the top. So imagine i have objects 1,2,3 and 4. 1,2,3 objects need to be randomly scattered across the surface but less of them at the top. Type 4 needs to be randomly scattered across the surface but almost 100% at the top.
I'm having trouble being able to do all of these using 1 Forest (ideally).
