I was watching the Iray render preview video. About 18 seconds in, there's a scene with a knight swinging a sword. In the background there's a torch burning. I was wondering if this effect was a popcornfx effect or was it achieved some other way? Can anyone shed some light on how it was done? It would really be nice if there was support for popcornfx but I'll settle for being able to do a campfire or a torch with Iray in some fashion. This is the video I was referring to.

Good observation. It can't be Popcorn or other particle, so what is it?
I looked closely at the clip and to me it looks like a video texture. There is no light coming from it and it is kind of flat. A video texture would render in Iray.

Truth be told, I would not be so hesitant to embrace Iray if there were support for PopcornFX. Reallusion spent so much time giving us these neat tools and then they give us a render engine that can't render them. It's like they forgot. So if I want to switch to Iray, I can't do fire or muzzle fire or any of the other wonderful improvements that have come through. Hopefully, someone will come to their senses and work towards getting their Iray render to support PopcornFX. Personally, I think it would probably be easier for them to get their built in renderer to do SSS. I'm a fan of specific plugins to a point --but not when it cuts you off from doing the things you want to do.

I have to agree. I have Iray and I like working with it, but there is no word about PopcornFX support. As I've said elsewhere it would be nice to know if it is technically impossible or if it just needs to be implemented.

I've often wondered about doing some sort of compositing, but I never seem to get around to doing the experiments.
Could you turn *everything* in your scene into some sort of light-and-shadow catchers and then add PopcornFX particles. The objects could maybe get "lit" by the effects, and also hide particles that fall behind your objects. Imagine everything being a flat black, for example, with no lighting other than the PopcornFX. Could you then composite that on top of your Iray render in your NLE?
I've not even had time to launch iClone for the last 3 weeks, and I miss it. I look forward to having "hobby time" again.

I understand what you're getting at Justaviking. If I really have to, I'm prepared to do something like that, but only as a last resort. The thing about iClone's native Renderer is that Popcornfx just works and that's a tremendous timesaver. If I did it, I might be able to accomplish it but how much time do you lose having to setup each scene twice and render twice in order to get the result you're after. You're losing a lot in the process. The thing that keeps iClone a workable solution is that it's fast. With Iray being slower you're already loosing a bit when it comes to speed. It makes it seem like you're erasing your gains when you look at it like that.
Still, I guess if you can set the scene up and render just the PopcornFX elements I guess you could make an overlay if you rendered an image sequence. I imagine if you used PopVideo 3 you could creatively remove the people if you were to render the people elements as a single color that you can use to make transparent in PopVideo 3 --then you could overlay the effects only on each image sequence. It's one of those things where if you want to take advantage of Iray you're going to have to get really creative to keep using your effects with it. I suppose I'll have to do some serious experimenting and see if it's possible.

Maybe someone else will do the experiment before I get around to it, but I picture how sparks fall and bounce off objects (or people), and some bounce in front of the object and some bounce behind it (and are hidden), so you'd need some sort of "invisible" object to make the particles behave correctly, so that when you composite it you get reasonably correct behavior. It might be a reasonable workaround for a way to blend PopcornFX with Iray. *Might*

In live-action film effects are combined afterwards all the time, so there must be established techniques. I just wish I knew more about compositing, which is a blank area for me right now...:unsure: :blush: :blink:

Hi animagic / Guys,
This is not a problem for me FX can be added in later using Ater Effects (post production editing using AE & Motion Tracking).
I have a question about Animations with NVIDIA
My pc spec:
Intel Core i7 7700K
Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz
RAM 32 GIG
SSD 860 1TB
MAXIMUS IX FORMULA
GeForce GTX 1070 8 GIG
Totla hard drives 6 total space (10TB)
So my question, I saw this demo video on reclusion’s website:
https://www.youtube.com/watch?v=-Yhy-YMnQYc
How long would it take my pc to output that video. Is it worth me getting another GeForce GTX 1070 8 GIG (as my motherboard can take 2 graphic cards)? Please advise as this is very confusing.
Best
Ian

Hi Ian,
i suppose you are only referring to any of these rendered clips that are put together using a compositing software.
As a simple example, to render a 10 seconds clip in Iray, with your card it would take at least a few hours (depends on settings).
You can imagine then how long it will take to render all the clips.
As for my own experience, the switch from a 1070 to a 1080ti almost doubled the render speeds for me.
I don't know if a second 1070 will do the same (iClone can't render on both cards at the same time to my knowledge).
Best regards,
3dtester

Iray is different from iClone in that it is a scalable renderer: each added GPU increase the speed. An additional card would close to double the render speed. Important: do not use SLI with the cards.
EDIT: Note that VRAM is shared so you would still effectively have 8 GB for a 1070.

Iray iclone does not support iclone water, iclone popcorn, light tools and few other iclone features, at 1st it didn't even support speed tree.
in my opinion renderman by Pixar should of been used, its one of the best render engines made on the planet and all the top end software
programs use it, its very affordable to. There is not a movie made today without it. its 600 bucks and highly intagradable with most 3d software.
this would of brought iclone to a pro level output. Iray was not designed as an animation engine.

Hi ,
On the matter of compositing I use an older (pre subscription ) version of Adobe Effects however there are other options such as Hitfilm Express and Davinci resolve and even sony vegas.
Compositing offers many advantages if you plan to get into VFX heavy types of animations but it requires some careful pre planning particularly if you have moving cameras.

No, unless you have very high end NVIDIA using NVLink the memory is not shared. You will be limited by the amount of RAM in the GPU with the smallest VRAM footprint. So if you have an 8GB card and a 4GB card, you will be limited to 4GB. Fortunately, you can get GTX 1070's for pretty cheap off of ebaythese days. I picked up a second Titan X Maxwell GPU with 12GB for $300. With two in my PC, my iray renders are pretty quick.

That's what I meant by shared: both cards have the same content. I believe that to be the correct terminology.
