编辑采用 2 vector3 的 Unity 着色器
Edit Unity shader that takes 2 vector3
这是一个来自 unity asset store 的果冻着色器，但我不知道如何让它始终处于活动状态，因为它需要 2 个 vector3（_ModelOrigin 和一个 __ImpactOrigin）。关于如何编辑它的任何想法始终有效？
这就是我现在使用它的方式:
modelRenderer.material.SetVector("_ModelOrigin", pos.transform.position);
modelRenderer.material.SetVector("_ImpactOrigin", pos.transform.position += new Vector3(0.001f, 0.001f, 0.001f));
但是当游戏对象网格太远时它停止工作
我也试过只使用 transform.position 但是当我移动游戏对象时，着色器会获得新值，所以它会延迟一秒钟
谢谢

最简单的解决方案是将它们作为属性删除，并根据对象到世界的变换计算模型位置，然后使用您的偏移量来设置冲击原点。
这样你就不需要在 c# 中设置那些参数，它应该“正常工作”。
