Trace over a 2D image?

How to trace over a 2D image, to create Mountains or various terrain features?
Looking for tutorial on taking a custom drawn 2D map and placing different terrain types over it.

This is very straight forward really.

First of all. Use a “File Input” to add your reference image, set its width and height. Then with it selected, press F to toggle preview lock.
Then add a Layout generator, double click on it, select “polygon” from the left side panel, and start drawing out your island shape.

Then you could use a series of Layout Generators and choosers to add in different types of terrain. Like lowlands and mountains.
Have a look at the example file “Islands with mountains and lowlands” to see how that’s done.

Hope this helps!
