Landscape layer info missing after adding more layers

Hello, Epic community,

First of I’d like to greet everybody since this is my first post on this forum.

Secondly, I’d like to get to the point.

I was using my landscape material with 5 layers and already painted something on my landscape.

The I decided I needed more layers so I added 2 more and saved the Landscape Master material.

After it was finished compiling, new layers did not show, so I restarted the engine. When I came back, new layers were there but they were all missing layer info, even the old layers which I already painted with.

Now, I could add layer info again to each layer but then I will lose what I already painted. I want to get back my painted info.

  1. I cannot add previous Layer info that was in that layer slot (marked with yellow arrow)
  2. 4 layers with ? Question Mark appeared which seem to hold layer info, but I can’t do anything with them. If I right-click I can choose to refill the material but that does nothing (marked with green arrow)

How do I get my painted Layer info back?
