This a jelly shader from unity asset store yet I cant figure out how to make it always active as it requires 2 vector3 (_ModelOrigin and a __ImpactOrigin). Any ideas on how to edit it is always active?
Thats how I use it right now :
modelRenderer.material.SetVector("_ModelOrigin", pos.transform.position);
modelRenderer.material.SetVector("_ImpactOrigin", pos.transform.position = new Vector3(0.001f, 0.001f, 0.001f));
but when the gameobject mesh is too far it stops working
I tried also to just use transform.position but when I move the gameobject the shader get new values so it becomes laggy for a second
Thanks

CodePudding user response：
Simplest solution is to just remove them as properties and calculate the model pos based on the object to world transform and then use your offset to set the impact origin.
That way you don't need to set those parameters in c#, it should "just work".
