Landscape material layer blend issue

I created a landscape material with layer blend node and hooked up 2 textures in. After that i proceeded to paint them and all was fine.
So I decided to add more textures into the material and I did. However after the compile is complete, newly added textures do not show under the options for paint

Any clue to whats going on here, or what I’m doing wrong?

Did you try to erase the 2 existing layers and rebuild new ones ?
Try to remove the material from your landscape and reput it in…
Did you check your blend by layer node in the material ? The name for each layer is good ?

I found the solution. Restarting the editor solved the problem

Marvelous !
