Memory Loss - How to create model

Here is something I created some time ago and I have forgotten how I did things. I have not used Skatter for a good while. I would like to create something like it again but am having problems remembering how to do things. I did look at some documentation, but I am consistently messing up. I can create the hills and etc. in SketchUp but when I try to add the vegetation (in particular I want to create just a straight line of bushes) and then add it to my terraine, I am making a pure mess.

Can someone give me a good place to go read (or watch a video) that will help me create a new model. I am not worried about rendering the model. I used to use Twilight Render and now I am looking at Rayscaper but I do think that is supported in Skatter. Again, right now I need some good advice on how to get some things done.

You can start with our tutorials: Tutorials | Skatter Help

And you are probably looking for Paint Masks and Curve Hosts.

Well, I think I am getting closer but am still having a problem. I you look at the screen capture below, how do I get the row of bushes “projected” to the terrain below the row of bushes?

I am still having problems with this issue. I have created a set of objects using Skatter that I want to project down to the terraine but have not been able to get it to work. I have done it sometime in the past but cannot get it to work again. I would like to get some advice on how to accomplish it.

What part of the process do you struggle with?
Is it projecting the curve onto the terrain? Or using the curve as a Host in Skatter?
