Mask and blends not taken into account

Hello,

When I try to edit files in \resources_common\terrain\blends or \resources_common\terrain\masks, this is not taken into account.
Is this a bug or is it normal?

Honestly, I think they are just there for usage for other artists/modders. (You are correct though. They don’t effect anything in game. I found this out a long time ago.) They are at least useful in that way.

I did the modifications directly in the game directory, but I don’yt like do that

If I recall correctly, I was able to edit the actual ones in the game files, bit I was not able to make mods of them work.
