My English is not good, so I use Google Translate to write this passage, I hope there is no ambiguity.
This is great material, I am trying to make a game, but I found a problem.
The middle part of the horizontal wall lacks separate tiles, that is, tiles with black lines on both sides: the 4th and 5th in the 3rd row, and the 4th and 5th in the 4th row. These 4 tiles have the same purpose. You may forget to add a separate horizontal wall when integrating the material.
I need this kind of tile to make the scene, although it is not a serious problem, because this kind of tile can be cut manually, but I hope you can pay attention to this problem, automatic cutting can not make this kind of tile.
Thank you for your work.
