I recently created three layerinfo for my terrain as non-weight-blended, but I realized that was a mistake after. It doesn’t seem like it’s possible to change that after the layerinfo is created, so I’m looking for a way to create new layerinfo… and it just doesn’t seem possible either. It’s not an option any more under “target layers” in the landscape painting, and I don’t see any option to do it in the content browser either.
They’re tied to your landscape material.
Add or change the inputs in your ‘LandscapeLayerSample’ or ‘LandscapeLayerBlend’ node inside your landscape material.
