Okay, here are 2 screenshots where you can see the spotlight problem i mentioned.
I disabled all other light sources to show the effect.





As you can see, as soon as the spotlight is inside the lamp housing, no more light gets emitted.

EDIT: i found a small workaround for my 'problem'.

Thanks, yes the iClone renders look better than i expected.
However, maybe there is not much in the scene that Iray can benefit from.
For example, if i had used IBL, the light from the outside through the windows would have casted nice shadows and created reflections.
But i didn't use IBL because with iClone native, IBL behaves wrong. And i wanted to only use light sources that are compatible with both native and Iray.
I could have placed a spotlight or directional light at the outside, but instead i decided to use only the light that comes from the environment sphere through self-illumination.
Of course, this is not optimal.


Ok, i tried different IES light shapes, which is a nice new feature that i definitely want to use.
But the problem is, the iClone spotlights and point lights can't be resized.
So they simply cannot match the bulbs of the wall lamps.
You can see this at the ceiling lamps. The light starts too far away from the ceiling.
I hope you understand what i mean, without having a close look at it.
For the wall lamps i used emissive surfaces (glow) with very high illumination.
This was (my) only way to achieve an acceptable apearance of the lighting.


Yeah, i want to test the new LOD features.
Have to find some good tutorial on this...


That sounds handy, and seems to really help encouraging me to get my ass off and learn python finally :)


:laugh:

Yo, nice comparison...
And native definitely is not bader than Iray in this case!

Dupe

I think the Iray renders you made look different, but not better.  The iClone ones looks great.

My little suggestions would be to add some IES light just to make interesting, and then reduce the overall lightness so that it comes off a little darker, but still lit where the lights are.

But my big suggestions are as follows, technically speaking, of course:
-Fill the scene with dozens, if not hundreds, of female avatars (Daz-based and CC3 alike) to really test out the LOD features that iClone now offers on your scene. 
(Importantly, you may want to limit clothing for this routine, if not exclude it entirely, so that the CPU is not overtaxed.)  
-Perhaps a python script-could be created to have all characters with towels remove them and place them on the floor, so that you can better calibrate all motion features in your environment.
-Finally, test some of the collision physics in iClone by having the characters make contact with each other, then gauge the success of the scene from there with all features in place.

Looks great! 

Well, i made a fool out of myself again.
But finally i find these iClone renders look not too bad.
Or what do you think?

Corrected metallic and roughness. Some displacement maps were also missing.
And there are no AO maps present in DAZ.

iClone native


Iray


EDIT: another confusing thing to me is the influence of image based lighting and self-illumination of props.
I thought i can use the sky image as additional light source from 'outside' (the scene is inside an environment sphere).
Here's how it looks without that illumination:



Slowly i'm getting somewhere. But i'm not sure if it's better.

Thank you!!
Metallic and roughness maps have been swapped by 3DXchange at import!
Every time the same, but i didn't remember  :(

this is why your lights look the way they do (like specular workfkow)

PBR




.

I guess you mean Ambient Occlusion.
Yes, it is enabled. But i didn't play with the settings.
Maybe that's the key to improve the light distribution a bit.


Thanks, my goal was to make it look close to the DAZ render.
It took me a while to setup the materials and lights :)
