I have multiple Material Functions where they are plugged into the Layer Blend node for the landscape. However when I add a tint to one of the layers, it automatically tints all my other layers.
Does anyone have any idea why that happens? I just want to adjust the color and value so my materials blend better?
Thanks
Maybe try making the tint a parameter in your material function and create and use a material instance and edit the tint there. You can create multiple material instances of your base material and apply them independently and edit the tint/parameters individually.
Hi Humanasset, thanks for the reply. The reason why I was duplicating all the MF is because, last time I tried instances, my unreal crashes whenever I hit shift + 2 to enter landscape mode. But as soon as I switched all the functions to individual master, the issue was temporarily resolved.
■■■■ I just tried replacing my functions with their instances, it works again now. No crashing at all
The issue has returned. Whenever I connect a function instance to the Layer Blend node, Unreal crashes.

Now deleting the MF_Desert_Sand node will crash Unreal as well.
What is going on? It feels like walking on eggshells, with everything I plug into or delete I don’t know if it will crash Unreal
Yes, everything I try I must do with caution because I don’t know if it fails unreal because of that.
