Question

我尝试统一使用svg文件

我在packagemanager中设置了矢量图形2.00

但是发生导入文件错误

我的svgfile的最大大小为2500亿个顶点和7mb

我知道网格最大顶点为4000亿，但我不知道精灵最大顶点

平均大小1600kb图片this

Vertex array is too large. A sprite mesh may not have more than 65535 vertices.

            // take the strokes into account, some triangles may appear outside the rect. We clamp the vertices as a workaround for now.
            VectorUtils.ClampVerticesInBounds(vertices, rect);

        var pivot = GetPivot(alignment, customPivot, rect, flipYAxis);

        // The Sprite.Create(Rect, Vector2, float, Texture2D) method is internal. Using reflection
        // until it becomes public.
        var spriteCreateMethod = typeof(Sprite).GetMethod("Create", BindingFlags.Static | BindingFlags.NonPublic, Type.DefaultBinder, new Type[] { typeof(Rect), typeof(Vector2), typeof(float), typeof(Texture2D) }, null);
      //it is error part

var sprite = spriteCreateMethod.Invoke（null，new object [] {rect，ivot，svgPixelsPerUnit，texture}）作为Sprite；

                    //it is error part  
            sprite.OverrideGeometry(vertices.ToArray(), indices.ToArray());

这不是结果

svg项目已删除

顶点数组太大。精灵网格的顶点不得超过65535个。统一
