Activating flow in the material when oceanrenderer is running does only work in editor

Current Behavior

I am checking for flow elements in the scene and activate all flow components then with this Coroutine:

    IEnumerator _flowactive(bool b)
    {
        var mat = Instantiate(oceanRenderer.OceanMaterial);
        mat.SetFloat("_Flow", b ? 1 : 0);
        yield return new WaitForEndOfFrame();
        _setCrest("_createFlowSim", null, b);
        yield return new WaitForEndOfFrame();
        oceanRenderer.OceanMaterial = mat;
    }

I use coroutine because it does not work synchronous. This works in the editor but not in any player. The flow itself works, but the rendering does not show the flow.

So before digging deeper, the question is: how much overhead does flow create, when there is no flow splines. Then I would just leave it on, if it does not matter.

Expected Behavior

I was thinking about it: maybe the shader is not available in the player because stripped during compiling?

Yes - the shader seems to be missing then - so let's leave it like that.
