I’m a total Blender (and 3D modeling) noob.
What I’d like to do is export an stl file of a mountain range that I can 3D print.
I have a greyscale png file (that represents elevation levels) I extracted from some USGS data and imported into Blender using Import > “Images as planes.”
I switched to edit mode and subdivided into 500 cuts.
Back in object mode, I applied a displacement modifier of the texture I imported, setting UV coordinates and the strength to 0.25.
I have a few questions:
Say my png image is 2500x2200 pixels, is the plane that is created the same proportions?
Most important: How do I get rid of the edges that are created (see image)?
How should I subdivide a plane to maximize resolution based on the resolution of the image I start with?
Is there a better way to do this than how I am doing it?
Any other advice you’d like to offer?
