Title: Atrium
Post by: dandelO on March 11, 2012, 06:14:24 PM
Couple of GI tests with this model, the first(empty room) uses just the sun and GI, the second(ivy test) uses 4 interior lights with GI.
It's hard to get the GI penetrating deep into the shadows so some strange envirolight settings were used. I know the common method is to use values of 1 for envirolight strength values and then increase camera exposure but it was never enough here. I used GI strength on surfaces=5 and strength in atmo=3.

* Some texture mirroring on the roof of the model that I'd normally fix in post but I haven't wasted too much time on this for now.

#2, with interior lighting only, no sun.

I don't remember the Ivy Gen' being so problematic with so many floating/disconnected leaves.

It's a pretty complicated model/environment. I wonder if that's throwing off IvyGen.

Interesting results so far though. That first sun+GI result looks pretty decent. TG's GI algorithm is not optimized for indoor stuff, but it's working ok there. I've actually always been curious what this classic GI test would look like in TG, heh.

I did a little post adjustment on them both but nothing major. Here's the first one without any balance/correction.

Wow.

Image 1 looks like movie quality to me. Image 2 has some issues as you already pointed out. WHat were your render times Martin, as expected or something else?

I found it to be rather stable but finicky nonetheless.

P.S. I know you mentioned the details Of the building before, but I cant remember now, did you Make this structure?

I didn't make it, no. The model can still be found here on the Crytek downloads page (http://www.crytek.com/cryengine/cryengine3/downloads).

I used really high render/lighting settings and that made the large image around 4 hours, the small one took 1. I could get that time down a lot with a little juggling, I'll update with more at some point.

Very nice images Martin :)

I did a test some time ago with this object. It is as you said not easy to light.
As Oshyan said this object does show that TG2 prefers outdoor scenes .

Yes, Ivygen makes more or less random squares, so not all leaves are attached. It's also a pity you can't hit several starting points for combined total ivy. You have to save each 'plant' by itself. At least, that's how far I understand it.
By the way, I think you need to reduce the leave sizes, Martin. And thanks for the link, it's a very intriguing model.

I can even imagine a soundtrack to the animation...  ;D

Jeez! You guys are further on with this .tgd than I am! :D I have started on animating something with this but it won't be done for a while yet.
Btw, I can also hear the soundtrack already, Mesocyclone. :)

Very nice work. Looking forward of the animation if you manage to finish it. What kind of rendertimes are you having ?
Title: Re: Atrium
Post by: dandelO on March 13, 2012, 06:15:57 AM
Cheers! :)

Freelancah, using a dualx2ghz it took me around an hour to render the smaller image on page 1 with RTE, with purposely very high lighting and AA quality. The large image was 4x that but again with purposely high settings. If it is animated, I'll need to cut that all back quite some. I'm able to half the time without too much difference in visual quality, I need more than that, and for less time still, though. WIP... :D

Very nice work dandelO, I've also been playing around with this model, but I can't get the floor to take the tile image or even a diffuse colour. Did you come across this? I've passed the model through Poseray and allocated all the image maps twice now and still can't get the floor to take any other colour/image. ???
Title: Re: Atrium
Post by: dandelO on March 15, 2012, 05:04:53 PM
Hi, Kevin. I didn't have any problems with the model. I opened it with Carrara, stripped the flag and fabric parts, re-exported to Poseray and saved for TG. All the textures worked fine. Carrara usually exports fine for TG on it's own but it's easier to check all the texture maps are loaded in Poseray. I'll see if I can upload the edited .obj anywhere later.
Title: Re: Atrium
Post by: Kevin F on March 15, 2012, 05:43:20 PM
Ha Ha! just sussed it! I had the model at 0,0,0 which puts the floor beneath the surface, so I was rendering the base layer! Just raised it off the floor and hey presto there's the tiles!
Thanks anyway.

Ah, good good. I had the surface disabled on the planet so I didn't notice that. :D
Title: Re: Atrium
Post by: dandelO on March 19, 2012, 01:06:40 PM
Please ignore the horrid blur/smear effects, even at high GI settings there was really terrible lighting flash between frames. I used GI 2/16/32 and it was still pathetic looking. The smoothing in the video was necessary to blend frames into one another, and still there is flashing.

This is why I never render TG animations with GI, there's really no way, at the moment, that you could sensibly use it with consistent light across frames. Roll on these GI improvements for animation that I've been hearing about.

Post by: Kevin F on March 19, 2012, 01:34:47 PM
That's still very nice though dandelO. The textures really look good on the stonework. But the GI improvements are really what's needed.
Did you re-scale the model to life size?
Title: Re: Atrium
Post by: TheBadger on March 19, 2012, 02:00:24 PM
I really want to thank you martin, for all of the experimenting you do and share.
This software would kill all of my patients without people like you lighting the way.
I truly hope this good nature of yours is rewarded.

I had enough problems without GI , in my animation Martin ;)  You have patience !
Title: Re: Atrium
Post by: dandelO on March 22, 2012, 03:11:10 PM
The sequence files looked horrible with default video settings, Kadri. I had to use some smoothing and blur filters to smear out the flickering, it really wasn't nice at all.

I used GI relative detail=2, sample quality=16, blur radius=32(this with a 'ray detail multiplier of '1', too). It was still terrible. I won't be trying to improve on it until there is proper, working GI that is able to be used in sequences, raising quality even further isn't really an option that I savour.

My video looked bad too (flickering etc.Used the same postwork).
But i had to use low settings to make it out before 2015 as Hannes is now heading :D
I really doubt that there is someone who uses GI settings (for animations) other then the lucky ones with a render farm near by :)

I can feel your pain when you saw the raw animation Martin !

Title: Re: Atrium
Post by: dandelO on April 02, 2012, 10:10:24 AM
Hi, Bobby. I just took it into Carrara and removed all the flag/cloth parts, resaved the object and imported it into TG(I'm not sure I even needed Poseray this time as Carrara saves nice objects that TG likes).

Of course, only the diffuse colour textures are intact, as always on importing a new model into TG, you'll need to reassign any bump/disp images(I just used the very same images as the colour ones for the displacement channel). Also, the plants and chains have alpha images that require reassigning, too.
It imported very well, the only real pain was navigating around the wireframe but even that wasn't too big a deal really.

hmmmm.....I seem to have not got the textures and the model I dl'd had no plants etc...got a link for the download mate?
Never mind , half blind, and I missed the link...got it now man....sigh.....

Well as I don't have Carrera but I do have access to an older version of 3DExploration at my boss's office and I was able to break it up enough to load all the  sections into Pose ray which I primarily use for compacting huge Object Lists into Material Groups making much more useable objects I can re merge in 3dX

My version, much smaller and lower res in another thread took 6 hours, must have been the reflections

Here's a trick I remembered from my Imagine3D days where interior lighting was always a problem.
I placed a completely featureless light [no shadows,glows, specular just light intensity and fall off] beneath the Atrium center and increased it till I liked what I saw. The render on the left has half the intensity of the right image
