1、Pass中添加
//添加GPU Instance預(yù)處理指令
#pragma multi_compile_instancing
2氧敢、VertexInput中添加
//為頂點(diǎn)實(shí)例化一個(gè)ID
UNITY_VERTEX_INPUT_INSTANCE_ID
3侯嘀、VertexOutput中添加
//為頂點(diǎn)實(shí)例化一個(gè)ID
UNITY_VERTEX_INPUT_INSTANCE_ID
//在頂點(diǎn)著色器聲明立體目標(biāo)眼睛字段輸出結(jié)構(gòu)
//與普通的GPU Instancing不一樣的地方另凌，XR的Single-Pass-Instanced需要添加這個(gè)宏
UNITY_VERTEX_OUTPUT_STEREO
4、Vert中添加
//（1）
//初始化頂點(diǎn)信息
//這個(gè)宏必須在Vertex Shader的最開(kāi)始調(diào)用
//如果你需要在Fragment Shader里訪問(wèn)Instanced屬性戒幔，則需要在Fragment Shader的開(kāi)始也用一下
//這個(gè)宏的目的在于讓Instance ID在Shader函數(shù)里也能夠被訪問(wèn)到吠谢。
UNITY_SETUP_INSTANCE_ID(v);
//（2）
//在頂點(diǎn)程序中，將實(shí)例ID從輸入結(jié)構(gòu)復(fù)制到輸出結(jié)構(gòu)
//在Vertex Shader中把Instance ID從輸入結(jié)構(gòu)拷貝至輸出結(jié)構(gòu)中
//只有當(dāng)你需要在Fragment Shader中訪問(wèn)每個(gè)Instance獨(dú)有的屬性時(shí)才需要寫(xiě)這個(gè)宏溪食。
UNITY_TRANSFER_INSTANCE_ID(v,o);
//分配立體目標(biāo)的眼睛
//與普通的GPU Instancing不一樣的地方囊卜，XR的Single-Pass-Instanced需要添加這個(gè)宏
UNITY_INITIALIZE_VERTEX_OUTPUT_STEREO(o);
5、frag中添加
//初始化頂點(diǎn)信息
UNITY_SETUP_INSTANCE_ID(i);
