Secrets of Stunning Lighting: Exploring Ambient Occlusion in Unreal Engine

[@raulgomez8523]

To have AO with Lumen, you have to use these two console variables. r.Lumen.DiffuseIndirect.SSAO 1 and r.Lumen.ScreenProbeGather.ShortRangeAO 0. And the AO will work with Lumen in real time. You should post a comment with that information, so others won't go crazy like me, until I found the solution.

OMG Thank you so much!!!! You saved me so much time. You are the real hero

After what I've seen from you - there was a desire to see a comprehensive - global lesson on ambient occlusion

[@bolbolegypttuber]

Thanks for this tip Just i ask how you do every camera with its own size ... did you make video to learn it !?

[@hotsauce7124]

how did you make the light profiles for the lamps?

[@ArchitectVirendraChhatria]

I tried adjusting intensity and radius of AO but its not showing any result

@@civareducation if possible please make tutorials on Ambient occlusion. How to activate that in unreal. I tried most of things but still its not visible in lumen render

​@@ArchitectVirendraChhatriaAmbient occlusion can't be changed with Lumen on

[@ArchitectVirendraChhatria]

@@amadorbom how to activate AO then?

Stunningg, are you done the modeling in 3ds max?

[@haneetkhanna1883]

always coming up with unique topics which nobody covers in detail.

[@artadecram_9624]

I reproduced all action you made and got nothing in aspect of changing AO - it doesn't work - may be it is neccessary to switch something on?

[@arthemos4627]

because in ue5 doesn't work anymrore. at least they are added It again recently but in a different Way, not what video showed. Surely adding which version he was using would make people lose less time

To have AO with Lumen, you have to use these two console variables. r.Lumen.DiffuseIndirect.SSAO 1 and r.Lumen.ScreenProbeGather.ShortRangeAO 0. And the AO will work with Lumen in real time. Test in 5.3.2.

Is this works with lumen and realtime no baking lightmaps?

[@tanyaabichaker4862]

Love your videos

[@erox3197]

How do i get such effect in baked lighting ? GPU Lightmss or CPU

[@martinmenso6671]

Could you explain how to setup this interior lighting, step by step. Struggling with getting enough light in my interior without blowing the exposure. Would be amazing

[@martinmenso6671]

@@civareducation Exciting! Any timeframe? Working on a project but just cant seem to get it right;)

[@K3Techs]

So, concerning realism, does ambient occlusion not conflict with modern lighting techniques such as RTGO (or Lumen for example)? I had always assumed it was a computationally cheap way to approximate the same effect

[@acsomiT]

Hi! What UE5 version u use couse on UE5.3 what you show it doesnt work?

[@civareducation]

Actually this video has been recorded on 5.1 and i have to make a new one on 5.3...

[@ahmadmp3267]

Hello, good time. Is it possible to guide me so that I can have great lighting like you? Please explain about the lights (from the settings of the lights you put in this scene) that will reach the light I want based on your settings. I appreciate it

[@hotsauce7124]

Thank you

[@avfxstudios]

please make a tutorial from scratch of lighting only. when i make renders it is like harsh shadows and lights. teach how to get this look n feel like yours please sir😢🙏

[@civareducation]

I will😉

[@RH_OPEN]

You'd better be careful about recommendations, now there are 2 users with troubles about AO, if you're using UE 5.2 the AO is not working at all from PPV, because if using Lumen the AO is deprecated.

[@tomasm1233]

Damn, I wish Blender would have this kind of control of ambient occlusion in Cycles. UE5 seems to be superior in that respect.

[@simenstroek7599]

It makes no sense to have fake AO in a true path tracer (like cycles). AO simulates a side effect of path tracing that doesn't come with fast realtime approximations like Lumen or SSGI because they lack the precision to do so.

[@tomasm1233]

@@simenstroek7599 It makes sense if you are an artist.

[@saimon1987]

Ambient Occlusion is THE OPPOSITE FROM REALISM. In fact, for Archviz, if using Static Lighting, you should NOT use Ambient Occlusion at all!!! I mean, this is all WRONG! Any occlusion that hapoens in real world gets baked in the lightmaps when using LIGHTMASS!!! So, no! You may want to use AO as an artistic addition or creative decision, but its NOT realistic. Quite the opposite! The same happens with offline rendering. Years ago they used AO passes for offline renderings very often. But we just stopped usinh that becaus its nit realistic at all. And the raw render already has baked in it all the occlusion that would happen in real world.
