Where do I need to add the draw node?

I am trying to generate mountains on an island which I created my own. I have drawn the island myself.
It is an island of `137 km by 106 km. The form island may never change. This is now completed.

However, I feel the mountains are too much concentrated and don’t feel good. I read that with the draw node, you can create your own mountains.

I tried everything, but it seems that no mather where I connect the draw node, the effect is zero. I cannot see the island to draw in. Any help? Or advice?

A couple of concepts to I think would be good to grasp here are:

  • Masking
  • Shaping
  • Blending

What the draw node is:

Manual input > mask > Heightfield

What is isn’t:

Your goal is then is to add the remaining stages to complete the workflow:

  • create the mask (/draw node)

  • add processors (shaping/erosions etc.) to create the object ( i.e. mountains)

  • then compose by blending/adding objects into your original work ( e.g. /combine / /transpose nodes) that can be further adjusted with nodes like /transform

This way you have a cleaner branch logic; parts can be created in isolated ways instead of being dependent on one another and you can add them together later.

Creating independent components this way gives you a lot more flexibility.

Where you seem most stuck is understanding how to compose your graph with blend modes/combine logic.

Hope that helps

Thank you for thinking with me! You suggest to start with a seperate route starting with the draw node? Am I correct? But the drawing should remain in my island shape, so I should connect the file node to the draw node? And then after shaping/ adding and eventually use combine node to get back to the original flow? But were in the graph?

I will try to get a more interactive sample to you soon.

But the gist of it yes.

The main difference is the masking step and when to connect.

You can build it completely disconnected at first, then when you’re ready to apply it use combine/transpose. Additionally using things like transpose-insert or a hard mask - like you have of the island, can help you build a constraint so that it doesn’t apply outside of the area and Transform, will help you to place it to your needs.

Here’s a quick demo of transposing into an explicit area.
