Hello, indeed, the cause of this shape is polygon packing combined with square or power of two settings.
Polygon packing is complex. When it is given a higher max size, it may try to fill in one direction while minimizing the other, and sometimes it may even pack worse when given more space as it cannot possible try all possibilities.
It may work to give a smaller number to the maximum atlas size, otherwise it might be best to disable polygonal packing if square and power of two are required.
您好，确实是造成这种形状的原因是多边形填充结合了正方形或两种设置的幂。
多边形包装很复杂。当给定更大的最大尺寸时，它可能会尝试在一个方向上进行填充，同时最小化另一个方向，有时在给定更多空间时甚至可能包装得更糟，因为无法尝试所有组合。
可以为最大地图集尺寸指定一个较小的数字，否则，如果需要平方和幂为2的情况，则最好禁用多边形填充。
