I updated my material in my virtual height field to use the stored visibility mask and everything works now.
I’m really confused though. Isn’t “Enable Edit Layers” supposed to be checked ON in order to edit layers? I have to uncheck it to modify the landscape layers.
edit: Ohhh… ok. So “Enable Edit Layers” isn’t to paint layers, it’s to add, remove or modify the layer itself (not the weight or height maps). And when this is checked, you can’t paint. In any case, this isn’t what was causing the whole thing to go black. I recreated my layer now that I can paint on it.
edit: Is there a way to update the visibility mask right away? I have to toggle “Enable Edit Layers” to see the changes.
edit2: Got it. You have to use the visibility mask directly in the landscape material and turn off the virtual height field.
