Need help creating ambient occlusion render pass

eiliestl

Trying my hardest to create a AO render pass in Daz using the UberEnvironment like the picture shown below.
So far no luck . Please help..

Step 1...create a primitive (cube, sphere, cone...anything). Then in the Surfaces tab for it, change the Diffuse color to 210, 210, 210. Scroll down to Lighting Model and select Matte. Then with it selected, Save As > Shader Preset. Name it something like DS Default blank matte. You can now get rid of the primitive.

Step 2

Load the items you want...buildings/etc. Then select ALL the surfaces for those items...and apply that preset that you just made. Double check your surface parameters...

Step 3

Load the UE2 base. Expand it in the Scene Tab so you can see the Environment Sphere...you are going to need to make a couple of changes to it. The first, in Parameters, is to Show Hidden and then unlock (looks like a little padlock on Scale)...then scale it up so your entire scene now fits inside. Then turn Visible in Render ON. Then under Surfaces for the sphere, make sure its Diffuse color and Ambient color are set to 210, 210, 210.

Now for the light part. Select the UE2 Light. In its parameters, select either of the two Occlusion options (usually it loads with Occlusion w/directional shadows as default). Then up the Occlusion samples to something like 128 (minimum) to 512 (maximum). Turn the shading rate to at least 8 (32 is way too high). Using the 4XHi preset is a good start...

A couple of other things, the 'environment' is defined by the Environment Sphere, that UE2 loads, when you turn it visible, that's why you need to scale it up. But if you are trying to do an interior scene, then you can probably leave it 'off'. But you will need to make sure that at least some parts of the 'set' will allow light in, if it's a totally enclosed space. This can be done by turning off the Cast Shadows parameter...

I couldn't scale up the sphere for some unknown reason. This is what I got . I wanted it to be a bit softer so I'll keep playing with the light settings .Other than that, this worked perfectly. Thank you..
