How to Add AMBIENT OCCLUSION in Blender 3.0 | Blender AO Tutorial

hey everyone this is android cemetery and in this video i'm going to show you how to add ambient occlusion to your models so first thing we want to do is select the model go into the material properties and then add new material then we want to go to shading i'm just going to move this over here for the time being i'm going to press shift a click on search and the first one on the list should be ambient occlusion just in case it's not you can always type it in here so i'm going to click it and move it over here i'm going to press shift a again press search and type in color ramp i'm going to connect color down here so i'm going to press shift a click and type in mix mix shader i'm going to connect this shader down here to the bottom one and then i'm going to connect the color to the factorial which is this one fac and then connect the mix shader to the surface so you don't see anything happen yet we need to be in the viewport shading and also make sure that you're on cycles so go to your render properties make sure that you click cycles and you can see that the model now has ambient occlusion applied to it in the settings you can adjust the distance of your ambient occlusion so you can see it's affecting a much wider area usually i tend to keep this as the default and with the color ramp we can adjust the amount of ambient occlusion we're going to put on the model so if i move this up you can see that the ambient occlusion is much darker now the reason why the ambient occlusion is very dark down here is because the ground plane is affecting the model so for example if i move this down you'll see it's not affecting the bottom of the mouth as much so say for example we want to keep the ground plane where it is and make sure that the ambient occlusion is not going to be affected by it we can go to ambient occlusion node and we can click only local and you can see when you hover over it it says only consider the object itself when computing ao so click that and you can see we've fixed the problem now i usually keep the ambient occlusion as black but you are able to change the color so if i move these out of the way if i press shift a search and type in diffuse if i plug that in i can change the color of the ambient occlusion now just to finish things off i usually make sure that when i'm rendering a model that the ground plane also has ambient occlusion and that just makes the render a lot more realistic so easily i can just select these three nodes click control c select my ground plane add new material move this out of the way control v connect my shader to the bottom shader and the mix shader to surface now you can see how the ambient occlusion is affecting the model a lot more clearer when i'm using a cube so for example if i just connect this back here you can see the shadow's nice but that's because i'm using a few lights but you can see when the cube is on top of the floor plane there isn't any ambient occlusion over here so i'm going to connect the shader back into the surface and i can adjust the color ramp to make it a little bit more darker and you can see that the render looks a lot more realistic with the ambient occlusion just make sure that when you copy these nodes over to the floor plane that you untick only local you can see when i had only local ticked it's not affecting the cube so make sure that only local is unticked so i hope you found this tutorial useful and i will see you in the next video [Music] you
