Layer opacity mapping for the entire terrain

Unity Engine

I know I can paint where my various Terrain Layers should appear, but is it possible to import a grayscale image to tell Unity what a Layer’s transparency should be? This way I could paint my terrain layer locations in Photoshop and import them.

Using the terrain tools, it’s possible: Import Splatmaps | Package Manager UI website

Thanks for pointing me in the right direction.

I am using Unity version 2020.1.6f1, I don’t see that in the package manager, is it only available for the 2019 version?

They are still available, however you now need to enable preview packages. There are instructions for how to do that here .

It is also possible to assign the alphamap values from code without using the terrain tools package.

Thank you, that extra step to enable the preview packages seems like a bad UI choice to me.
