Tree line and populate.

[John]

I am a newbie. Would someone please point me to a step by step instuction on how to make a tree line and populate it?
Thank you.

Do you mean a line of trees or the "tree line" where trees no longer grow due to their altitude.
If the former make your self a mask in photoshop and use it as a blending shader (make sure to set your image to plan y)
If the latter use a "Surface Layer" as your blend shader and set its max and min altitude to your desired height.

I meant the latter. I would like to set the max and min altitude on the side of a mountain, then populate it with trees or whatever. 
Any hints or tips on populating from anyone would be welcome
Thanks for the reply.

You know how to get a population, right? And how to place it? Good!

Now. Create a surface layer node in the node view. Chenge the name of the node in whatever you want, and copy it with ctrl-C. In the population settings there is an option to 'use density shader' with a textbox next to it. Paste the name of the new surface layer there with ctrl-V, and you have a density shader.

In the surfeca layer, set the desired slope constraints and altitude constraints, and populate the population. If you enable 'preview instances' you can see if you did it right, or if you need to change some things.


I hope this helps you enough.
