#VrayFor3dsmax #OccPass #AmbientOcclusion
In this tutorial, you will learn how to turn your amateur 3D renders into Professional 3D renders. you will learn "Ambient Occlusion" also known as "OCC Pass" trick that is used by almost all the professionals. This trick adds realistic soft shadows to your 3D renders which makes your render amazingly realistic.
If you are thinking about how to do ambient occlusion?
Then you are in the right place. You will learn 2 methods to do ambient occlusion.

[@SWKTutorials]

I'm glad it was helpful for you

[@endavidg]

Thanks, that's very helpful! However, I'm not sure about the wording. I think adding fake Ambient Occlusion doesn't make things more real, but more fake. Not sure if "more fake" can be called "more professional". At 11:57 “this is how I changed my flat 3D render into a professional 3D render”, the flat one looks more real to me. The “professional” has made the light from the window go away and everything looks slightly toyish. The light from the window should bloom if anything, but with the extra AO it doesn't look as a window, but as white paper with shadow projected on it. Humans tend to prefer more AO because it increases contrast and we are contrast junkies, but it's not "more real" or "more professional", I would say.

[@GFYGames]

very well explained ...
I have a problem. why can't i change the values to subdiv. remains locked on 8

[@SWKTutorials]

Yes. In newer versions of VRay it is locked by default. When you increase render setting in render setup window it will be automatically improve subdivs quality. The number will remain 8 and locked but quality will improve.

[@GFYGames]

I had shown 2 methods for adding ambient occlusion. Kindly see method 2. It will work with GPU.
While both will work with normal VRay

You don't need to change subsivs. It will automatically be calculated according to your render settings.

[@deepakk2699]

Can we use this for exterior rendering ,, and also one more dobut there is ambient occlusion map for every pbr materials we download how we use them

[@SWKTutorials]

Yes. You can use it for exterior rendering. Product rendering.
PBR materials is something totally different. Don't mix ambient occlusion pass with PBR materials.

[@SWKTutorials]

For PBR materials I will make a new tutorials in this month.

[@deepakk2699]

[@deepakk2699]

And I also have a request please include tutorials for making complex pbr materials with out any help of material maker scripts or apps ( in 3ds max vray and also in others applications)

[@SWKTutorials]

Ok. I'll put them in my tutorial list.

[@ricr8987]

there's a way to apply the AO texture to material?

[@SWKTutorials]

Why do you wan't to use this technique. We use to do it in other rendering engine. It's an old technique. My personal suggestion don't do it. It's a cheat. we use to create fake GI effect.

[@user-sj7xg9cl7c]

Not bad vid
Results begins problem card graphics & old hdd drive 😁

[@SWKTutorials]

This is the issue with 3d softwares. You need latest graphic cards and fast system

[@SWKTutorials]

I'll be doing blender tutorial after some months.

[@shailabhsuri1772]

where to put AO map while texturing an object?

[@SWKTutorials]

Ambient occlusion map used in texturing is something extremely different.
This method add details to the whole scene.

[@DanFrederiksen]

That's not how pros do it though... AO is a hack

[@SWKTutorials]

I am working since 2005 in 3D field. The compositor always ask for an AO pass, along with other passes.
First you do the normal lighting.
When you finish the lighting.
Then at the end along with other passes you give compositor AO pass.
It's not a hack.

[@DanFrederiksen]

@@SWKTutorials do you see other vray render tutorials here use AO?

[@SWKTutorials]

First, I don't look at other people channels. Because I know VRay from working in field.
Second, do you know about render passes?
Third, If you don't like it. I'm not pushing you to do it. But when you go to a big team. Who have compositor you will understand what I'm taking about.

[@SWKTutorials]

Just learn about render passes.

[@DanFrederiksen]

@@SWKTutorials Maybe you should look at what others do before declaring professionals amateurs.. you can observe that others do flawless photoreal visualization without using the crude game hack ambient occlusion. I understand you can cheat a lot in compositing with a good artist and if the GI resolution isn't great I guess AO gives you some darker corners but it's not the only way.
