Age of Armor's Atmospheric Effects and Iray

LiquidWarehouse

Does Age of Armor's Atmospheric Effects work with Iray. I've tried it several times now and fail to get any kind of effect out of it, and have to resort to the SSS cube which raises rendering times significantly.

No, it wouldn't as it relies, so far as i know, on the features in RSL for it to work.

Ahhh ballz :(

There are tutorials on how to get atmospheric effects in Iray without purchasing any products.
This is one that I am playing with right now. https://sickleyield.deviantart.com/journal/Tutorial-Creating-Dust-And-Atmosphere-in-Iray-522291773 ;
Only one slightly confusing bit

"Scroll down to the Refraction.  Set the amount to maximum"

"amount" = Refraction Weight

Using the above tutorial as a guide for how to set up the volumetric area, this is what I came up with after a few test render starts, and setting adjustments.

Just over 2 hours rendering for 15000 itterations on a GTX 1060 6GB card. (finished at just over 30% convergence!)

Hi James,

nice work.
Something is not working with the link to SY's tutorial, you posted. I get 404.

But anyhow. I did it it the "normal" way: Using Transmission and Scattering. And with a "little trick" I even succeeded to have my camera inside the foggy volume.

I don't know why the address isn't working... If you go to deviantart and put this into the search without the quotes "Tutorial-Creating-Dust-And-Atmosphere-in-Iray" it will be the first result.

There's an extra space at the end of the link...

Yep,

that's a tricky link. The "%A0" substitude at the end was the fault.
It is the old, well known tutorial with useful settings.

This is the trick i've been using but it's very render intensive.

Volume effects are always render intensive; it's one reason people use cheats or postwork.

Epic God ray product is useful as a somewhat sleight of hand way to do it much more quickly, but you have to have more care with how you set it up.

JamesJAB

I will happily choose the longer render time and do it right without tricks or post work.

My goal is to create images that do not need any postprocessing.

Oso3D

Why?

Hmm, so IRAY is no tricks ;) why care about how a render is done, the only thing that matter is the final result and if you can do something in post that takes 5 minutes instead of waiting 2 hours for a grainy render, why not do that instead, in render effects and post effects both have their place, use the one that works best.

For me I enjoy the process of how things work, as much as the final render.

For example, on my above render... I started that render 15 or so times, to see how the lighting was interacting with the "dust" in the air... I would render about 30 seconds each to get a few good Iray canvas draws, then tweak the light angle, or the amount of "dust" in the air.  Then when I was happy with that, as the render progressed, I adjusted the bloom settings, exposure values, crush blacks, and burn highlights settings.

15000 itterations later I have a final image that needs no post processing.

On a side note.  If that image rendered long enough to hit 100% convergence, it would probably look odd.  An image captured with a camera in that lighting setup would be grainy, because it would need to be shot at a high ISO value (or on fast film).

Yes, I enjoy the journey as much as the final render.
