自定义shader，不能显示动画
你好，我想问下，我不用surface，用自己定义的shader，添加了 #include "AnimationInstancingBase.cginc"，但是不能正确显示动画，能否提供一个自定义shader的例子？

很感谢您能回复我，上面我是我修改的一个卡通shader，里面包含了ｇｉｔ上说的两段代码，在我的场景中，如果把instance的物体的材质换成本来就有的surface，就可以显示动画，但是如果换成我上面的那个材质，就没有动画了，能否告知下原因？
看你的shader，里面定义了自己的vs，所以才没有动画。 你把这个shader的vert()注释掉应该就有了。 如果你想使用自己的vert()，可以参考AnimationInstancingBase.cginc里的vert()来修改一个自己的版本。
您好，我按照您说的把下面代码注释掉了，没有修改AnimationInstancingBase.cginc中的vert() //v2f vert(appdata v) { // v2f o;
// //UNITY_SETUP_INSTANCE_ID(v); // //UNITY_TRANSFER_INSTANCE_ID(v,o);
// o.pos = UnityObjectToClipPos(v.vertex);
// o.uv = TRANSFORM_TEX(v.uv, _MainTex);
// o.uv2 = v.uv2;
// o.normal = UnityObjectToWorldNormal(v.normal);
// o.color = v.color;
// o.wpos = mul(unity_ObjectToWorld, v.vertex);
// TRANSFER_VERTEX_TO_FRAGMENT(o); // TRANSFER_SHADOW(o); // return o; //}
运行场景后，出现一个破碎的剪影，这个剪影的动作是idle，是正确的，但是他的贴图不正确，大小位置也不正确，场景中，也会实例化对象，但是不能正常的显示动画
这是什么原因啊，如果您有时间的时候帮忙解惑下吧，迫切想用您的这个技术做个项目，谢谢了！！
你的shader里有2个pass，你是不是只注释掉了一个？ 另外Outline pass这个pass也许要加上#include "AnimationInstancingBase.cginc"
您说的那点，之前我自己也尝试过，也是不行，现在我重新定义了一个很简单的shader，出现的结果也是不正确的，目前，我没有修改"AnimationInstancingBase.cginc"中的任何东西，运行后，还是不显示动画，我很费解，我有尝试重新做Animation Generator，重新做AB build,重新BuildAssetBundle，还是不行，我有看到别人留言过，自己定义shader都成功了，我尝试了无数次了还是不行，真的很抱歉，又来请教您了
