When there is an object in the scene with reflections-mirror2 and water(Pro) with reflections, the first all right, but when I exit the program and reopen the scene reflections no longer work even if the names of the textures in the script are different:

m_ReflectionTexture.name = "__MirrorReflection" + GetInstanceID ();
k_ReflectionTexture.name = "__WaterReflection" + GetInstanceID ();

How can I fix it?
