Post Process Volume Material Exception

Hello,

I created this (Unreal Engine 4 - Heat Waves v1.0 (Materials) - YouTube) Post Process material and assigned it to a postprocess volume trying to simulate heat waves… However i found out a problem, what if i do not want apply the effect to the entire scene, i mean, how do i tell to not apply that Post Process material to some StaticMeshActor for example?

Here is the material:

Thanks.
