Google Translate : For example, spread a minimal project in which this bug is visible! Describes the essence. Prefab create a cube with a texture. I write a script that adds to the scene 50x50x10 cubes. The result should glade of cubes that can be navigated with a first-person! But the editor I have an error maxVertices <65536 & & maxIndices <65536 * 3 And in the build,part of the cubes disappear and visual bugs. What am I doing wrong? And seen whether this bug you? If not hard to see the project
