help for height map

Hello, I’m encountering an issue with my height map. Every time I bake my high poly map, the topology of my low poly is visible. I’ve tried everything, from exporting to adjusting the bake settings, but I don’t understand why. I’m using 3ds Max to export my low poly, and in Substance, I get an error message that appears. Have you ever faced this issue? And do you have a solution?   [EngineBitmapLoad] Failed to decode bitmap.
