double AO

Greeting!

About global Ambient occlusion - (just learning UE)

As i know i can make global AO in unreal engine scene but i can already have AO on my 3d-object and i don’t need it again

We can apply AO to all in the scene but if already have made AO in substance painter - that means that AO already is done on my 3d-object that is on the ground - i don’t need double AO - how can i exclude my 3d- object from global AO?

I suppose that AO made in subs-painter has more quality and made more subtle so i need to have it untouched
