Flickering that looks like a 'lighting' problem is usually caused by GI.  From what I've seen in the RL video about 'optimizing' for animation it looks as if iClone is still generating a batch file of individual frames to the Iray renderer - the MI file (a slightly more sophisticated version of our beloved Indigo pipeline!).  So, in short, if the GI is recalculating for every frame you will get flickering...  if there's a way to 'disable' GI it may be worth trying to see if it rectifies the problem (although what's the point of raytrace renders without GI?).

@4u2ges .... I get what you're saying: it will never be perfect, but the question is how close can you get?
This is the exact same file as above, run though VirtualDub's internal temporal smoother and the result is decidedly better.

@Charly .... these took around 43 seconds per frame (1920 x 818 pixels) done on a single GTX-1070 (Laptop), so this 17 seconds (400 frames) took around 4.8 hours. (repeated on this video).

Unfortunately it cannot be.  It could be 40 or 400. The result in Loft Scene case would be the same.
That is a nature of Interactive mode rendering. Fast but inaccurate, or rather inconsistent in dynamics.

Good Steeve, good. And the render time was...?


     

Well here's a test I knocked up for the Loft Scene ...
It was done at just 40 iterations per frame. This helped immensely with the render 'time', but to be honest I'm still not happy with the 'quality' due to the persistent *flicker* even after filtering (seen mainly on the walls).
If that could be eliminated, it would make for incredibly efficient Iray renders. So the settings used for the render below were exactly as mentioned at the beginning of this thread.

Thanks Snarpe for your thoughts here .... and yes - I too find myself mostly 'playing around' in iClone (I've got a long, long way to go - heaps to learn yet). I'm not at all familiar with 'scripting' or 'programming' of any sort; I'm just a visual guy that wants to get the 'look' I like with the *minimum* amount of fuss. The way I see it, the 'less' that comes between 'idea' and 'end product' - the better. I don't know how those with all the programming skills can come from 'that place' (technical), and yet be 'creative' as well. - It honestly does my head in. Well, of course, *if* you can do both that's terriffic! - It's just that I personally can't. I'm a 'what you see is what you get' sort of guy (the way I work) ....

Interesting what you say about DAZ, (which I've had very little experience with, so I can't compare the two), but I do think Reallusion have done a good job with the Iray adoption. I'll possibly always be a grass roots, basic creator sort of guy (or even more of a 'tester') - but I do 'aspire' to great things. If they're ever going to happen, it'll probably be with iClone ..... 

Well I do wish you well with your endeavours Snarpe!  :)

Thanks Steve for posting this!

I've been playing around with Iray settings too but don't really know what I'm doing yet, just playing around to get a look that I want.  Most of my work has been in still images, for the magazine articles that I've written, and your settings should help with that, but then again all that is about to change. 

I've given notice to the Voice magazine that I am retiring from writing my articles, after 10 years I just don't see the views or feedback I used to get, instead of thousands of views I'm lucky to see 100!  They have asked me if I would be interested in doing a comic strip for the magazine, and I may play around with that idea, as each one of those I do would be from scenes that could eventually turn into a movie!  This will free me up to devote more of my time into learning all the parts of animation and film making that I've had to put on the back burner for so long. 

I'm excited about Reallusion's Iray finally coming into play and am impressed with the quality of the speed settings, compared to DAZ render times of a 3840 x 2160 at over one hour, I can get the same or better render quality in just a couple of minutes!  The difference though is that in DAZ I have a plethora of pre-render scripts that I can use and they come with camera's, shaders, backgrounds, sky domes, etc., etc..  When I get into iClone I'm kinda lost as how to put all this things into play and just play around sometimes for a whole day to get what I think looks good, and so I'm hoping more people will share they're settings too on this thread to help with the learning curve!

@4u2ges ... Looking forward to viewing your pics full screen this evening when back at a PC & internet source. Plus I can try some actual tests tonight. :)

Thanks Ani for additional tip with Notepad++. I was too lazy to add that one. :)

4u2ges, thanks for the Firefly Filter tip.

I was looking for a way to make changes in all scene files for a particular scene and found that you can do this with Notepad++.

Open Notepad++ and select Search > Find in Files... This will open a dialog box:

75% of original size (was 671x19) - Click to enlarge

Make sure the "Extended" option is checked.

In "Find what" enter: "iray_firefly_filter" true

In "Replace with" enter: "iray_firefly_filter" true\n\tattribute scalar "iray_nominal_luminance" 150

\n gives a new line and \t is a tab to indent the line with the rest.

In Filters: enter: *.scene.mi

In Directory you enter the path to the MiResources folder where the scene files are located.

Click "Replace in Files" and all scene files will be updated.
