Unity 打包Java堆栈空间问题解决方案

   Unity打包一个场景几百万个面数打包一直打包不出来，网上搜寻答案，很多是让改JVM参数，跟着改了好多。但是问题依旧存在。以下是我对场景的面数进行的计算以及结果。可以发现支持的面数在500万左右。无论是动态加载还是分多场景加载结果也都是失败。此时很重要的一点我使用的是Unity个人免费版。

  后来无奈我开始更换不同的机器不同的个人免费版本结果依然一样，最后更换了Unity pro版本再次打包成功打包出来。

  最后附上我的错误提示供大家参考:

CommandInvokationFailure: Gradle buildfailed.
