some new images in Brazil

[AdamT]

Thanks, I wasn't sufficiently jealous before. :)

Is brazil a C4D render-system? Allways thought it was a max plugin...

It is--not sure why this was posted in the Cinema forum.

Claudio Crosio, what is happening to you????????????
I don't see you, I don't hear anything about you...

I've sent you some emails, even PM's here...... are you ignoring me for some reason, I'm wondering...?
If yes, say to me why.

VSL.

[Claudio72]

Ciao Stefan, I'm really busy at the moment but I've aswered all the email you sent me!

Why you say something like that?? I'm not ignoring you!!

[kiwi]

Thanks Claudio :thumbsup:



I think our render engine is as good as those Brazil images :)



Stu.

[Claudio72]

Yes, I think too!!!

Maybe in the translucensy and the toon shading brazil has something more to say......

[AdamT]

We certainly don't have the chromatic dispersion effects that Brazil has, or micro-poly displacement.

[Claudio72]

you mean this?

the aberration?

Yep, I mean that. Your XL7 trick looks pretty good, but not as good as the real thing. How'd you do it?

[VSLX]

Well, how can I know... I mean, you get lost, I knew you were busy but then the emails were not coming and I started thinking, heh:)

Well, it's ok. I was ver busy too, and I still am... but I'm getting some more spare time for personal projects.
I wanted to keep working with Splashchallenge make it active again, to open the STORE section, since I have new print works and too see what you think.

But we have to talk one day on ICQ...

I hope you are doing well:0

[Claudio72]

I use to be on msm now, the nick is my old email address

for splashchallenge I would like to do something new that keep me free because I definetively cannot manage it as before!



Adam, download it here, it's a nice trick and easy to improve too

BTW I know brazil has more control and especially a true control over the aberration!!!

[flingster]

thanks for the zip claudio72 was just gonna ask how ya did that.
:thumbsup:

I forgot you old email...

Here's a little experiment I did in Cinema XL7 last year with caustic dispersion. It's a crazy procedure, but it's actually physically accurate, so if anyone's interested, I'll post some instructions on how to do it. You must have the patience of Axl Rose, and be willing to fake like Milli Vanilli.

Hi, Brent,
I'm interested in that effect, and your glass material seems very realistic.

[AdamT]

Looks damned good, Brent. Bring it on.

P.S.: the patience of Axl Rose?

[ThirdEye]

Didn't know Axl Rose was that patient :shrug:

[michaeli]

I just remember that there's a very cool chromatic dispersion effects pic in Postforum who just use Xpresso to do it, but I can't remember who posted it and can't remember which thread it is. :(

yeah but that fake was insame, using scene motion blur and moving and changing the colour of the light with each render. Common prectice, and most say its more accurate than the spectral shader fake, but I beg to differ, it typivally prodeces fairly even bands even with odd sheped caustics, and gives an odd effect to the specualrity that shouldn't be there, but is because the speculare moves slightly with each exposure of the SMB.

[Claudio72]

it's people like you can change the history kaiskai!!! Don't stop!!!

[JIII]

Instructions please Mr. Turbo. I would really love to know how that is done.

???I'm just saying that since both are fake why bother with the 25 frame render. Tilll we get a raytraced Chromatic aberation its going to be a fake and R8 comes with an easy to use one built in.

[Claudio72]

......and this is what I ment, there's not so many people know what you know........if you don't post this message, we both render that 25 frames...........do you understand??? I'm not joking!!!

[LucentDreams]

ahh, well for those with R8 a simple scene I believe is included of the gem done by Toshihide Miyata and myself. Its a handy example of the speetral shader, and using basic highlights and caustics. The sample was posted on Mash's site a while ago, but the quality is quite comparable to the fake using expresso version. neither is perfect they have advantages though, the expresso one is typically a little more saturated spectral caustics renders faster.

and on a note about what I know, I'm just lucky to learn from people here and on postforum and in the beta testing environment. The R8 tips and trick, most were figured out by more than one tester, I just tried to document them and share them on the forums ;)

I can say with certainly that I have no idea what was being talked about in those last few posts... :cool:

Yeah, my method is totally insane, to say the least. It works like this:

1) Render your image as a multi-layer, but forget about caustics this time around.

2) Set up a new pass with only your caustic layer turned on.

3) For the caustic emitting light, you'll need change its colors properly according to light frequency. Since Cinema doesn't have that ability built in (or at least 7 didn't), you have to use a .mov file over the light to get it to cycle through the spectrum. I just happen to have one here: http://brent.dreamhost.com/caustic.zip

4) Create two materials for your glass object -- identical, except for their indecies of refraction. They're WRONG in the zip file above. The second material's index should be only about .012 higher than the first material's. So like 1.550 for the first, and 1.562 for the second.

5) On your timeline, give the object the first material in frame one, and the second in frame two.

6) Fill in all the steps I probably got using your detective skills, magnifying glass, and tweed hat.

7) Turn on scene motion blur at 25, and leav your computer on for an eternity while it renders.


That should about do it. No, it's not perfect, but if you want to impress your friends and neighbors with a render that "can't be done" in Cinema, then this is the way to do it.

P.S. "Patience" as in the Guns n' Roses song. Did no one else own a copy of "Lies" back in the day??

Thats the process we were discussing, and using the 25 frame motion blur, though instad of two textures it uses one light with its colour changing and moving slightly. this one wouldn't have the same specular problem which is good, but now your whole lighting is going to be slightly odd because of the coloured light, see each fake has a flaw. I still prewfer the spectral shader which is free for XL 7 by the way just visit the cebas site to get it. Its quick and easy to set up and doesn't use SMB so its 25 times faster

[Per-Anders]

it's true, but teh spectral shader does something totally different

spectral will give you an "oily" surface, the effect of a "thin film", whereas chromatic abheration or however it's spelt, is the prismatic effect that's dependent on the depth and density of the object, (i.e. it's volumetric as opposed to surface based).

and it does look totally different, the spectrum colours of a texture or a light looks far closer than teh spectral shader ever will.

Not really, though, since the caustics are done on a whole different render pass than everything else. First, you render the whole scene out with no gels on the lights, and then do an entirely separate render with the colored lights, and then composite them together later.

I hope whoever did the moving light version gave me some props -- I introduced this technique quite a long time ago on Postforum!! hehe...

I realize this isn't the most perfect way in the world to get some color spewing out of your glass, but if you can't live without the effect, and you must use Cinema, then I don't see why not!
