很抱歉给你带来麻烦。不幸的是，多边形打包可能无法实现纹理的最佳位置，因为它的计算量非常大，需要相当长的时间来打包以找到完美的位置。因此，建议你看一下导出的结果，如果有大量的空白，你应该减少最大高度和宽度，然后再次导出。
Sorry for the trouble. Unfortunately, Polygons packing may not allow for the best placement of textures because it is very computationally intensive and would take quite a long time to pack to find the perfect placement. Therefore, it is recommended that you look at the exported results and if there is a significant amount of blank space, you should reduce the maximum height and width and export again.
