unity中导入spine模型，当模型挂载SkeletonMecanim组件后，发现材质球向shader传值失败，改为SetPropertyBlock后可行。

//spine模型使用材质球传参数，当spine模型上挂载有SkeletonMecanim的情况下，会传值失败!!!!// foreach (var mat in m_SkinMaterials)// {//     int ShenshiIntensity = Shader.PropertyToID("_ShenshiIntensity");//     mat.SetFloat(ShenshiIntensity, _value);// }int ShenshiIntensity = Shader.PropertyToID("_ShenshiIntensity");List<Renderer> rendererList = m_Actor.GetAllRenderer();for (int i=0;i<rendererList.Count;++i){MaterialPropertyBlock pb = new MaterialPropertyBlock();pb.SetFloat(ShenshiIntensity, _value);rendererList[i].SetPropertyBlock(pb);}
