What is the correct format for Landscape layer maps and how to import them?

I’m creating a large landscape, height maps et layer maps have been created in world machine and exported as bitmap.

I’ve succesfully import the height map but I still can’t import layer maps. I can create new one from the editor but I can’t import my png layer.

What is the correct format for layer maps and how to import them ?

Any Ideas ?

Hi Cat-3D,

What program are you exporting from? When you export, what settings are you using? And can you screenshot your layer before importing to the editor? Also if you are comfortable with sharing it or a test asset, we would be more than happy to have a look and see what we can figure out. Thank you and have a great day!

Thank you for your answer,

I’m using World Machine 2. My exported layer map is an simple 8 bit greyscale png file.

My real ask is “how to import it into the landscape système”, when I create some landscape layer directly into UE4 these layers are in a special format. So how to configure my greyscale map to use it into the landscape system.

Thank you for your time !
