看到官方案例里面，有实现描边的多pass方案MultiplePassOutlineMaterial，我的目标是：实现角色被遮挡部分特殊效果显示，里面要用到模版测试，发现renderState中有模版测试的设置，但是发现没有起到效果，而深度测试起效，模版测试不起效，导致角色自遮挡部分也会特殊效果显示，这不是我想要的，请问下官方，这种方法是否支持，我也看到官方关于模版的demo，里面有对整个Material的renderState的模版测试设置，开启关闭后，小球显示，隐藏，是有效果的，不知道官方是否支持多pass的模版测试，还有就是自定义shader里面，是否支持模版测试代码定义，这样方便资源管理。
