【问题描述】：

我尝试统一使用 svg 文件

我在包管理器中设置了vectorgraphics 2.00

但出现导入文件错误

我的 svgfile 最大大小是顶点 2500 亿和 7mb

我知道网格最大顶点 4000 亿，但我不知道 sprite 最大顶点

平均大小 1600kb 图片this

【问题讨论】：

看起来您需要在导入之前简化要导入的文件。
@RobertLongson SVG 裁剪简单吗？如果你剪切一个svg，你能确保在屏幕上显示不同的svg时，彼此的位置关系不会被破坏吗？
并非如此。您可能会发现像 Inkscape 这样的 SVG 编辑器具有一些简化 SVG 文件的功能。切割和重新组装对于此处的问答来说过于宽泛，您需要尝试并提出更具体的问题。
您可以将Mesh.indexFormat 网格索引器格式更改为UInt32，它最多允许4,294,967,295，但您真的不应该开始使用反射...看起来一般您应该采取那里的不同路线
你为什么不例如使用正确的 Sprite.Create(Texture2D, Rect, Vector2, float) 重载 ... ?
