Hi, Im using Unity 4.3.3 ( I cant use 4.5+ because the paltform I use doesnt support yet). Im trying to do OneWayPaltform. I use a trigger to call Physic2D.IngoreLayerCollision to ignore platforms, but if I already colliding with one platforms Unity doesn't ignore that platform in specific even though the matrix collider show the ignore layers set correctly. Why this happens??
