Zeshio, i'm using stock settings for Hex Kit so there should be no problems from the beginning. You mentioned that you're not using Hex Kit for a while – is there any other programs where i can use your tiles set? Hexographer?
Hey man, I know this is an older post but when you click "file" then "New" there should be a tick box that says "Horizontal" in the options. You need to tick that to use this hex pack in Hex Kit correctly.
