UnityでMVP行列を自前で渡す

//各行列の取得方法

var viewMat = _camera.worldToCameraMatrix;
var projMat = _camera.projectionMatrix;
var modelMat = _gameObject.transform.localToWorldMatrix;

//シェーダー側

float4 worldPos = mul(_ModelMat,v.vertex );
float4 viewPos = mul( _ViewMat, worldPos );
float4 projPos = mul( _ProjMat, viewPos );
