Hey Lee, a few thoughts about your scene.

I understand it’s still in progress, but might give you a few ideas, anyway …

Keep an eye on the black points, first of all the background plate seems a little high in contrast. The Smoke needs to be much darker to match the plate, play around with the levels/curve in AE and match the blacks to that of your plate. That said i’d first pull the plate back a little then match the smoke to that.

When using AE, do most of the grading in AE itself so you can work with the CG at the same time, i’m guessing you graded the backplate in PS then imported into AE?

Regarding composition, i’d think about a different angle for the meteors, crossing the frame like that seems less exciting, maybe you could have them passing over the camera from slightly behind to the left, with a little camera shake, giving the impression they’re a lot closer.

I’d also like to see a little more internal glow/fire, at least 25% further up the shaft.

I’d also be tempted to begin the shot with a few distant meteors breaking through the clouds quite slowly, then introduce the two forground.

Over all looking good :slight_smile:

Hey Dave,

Thanks for the suggestions. I did all of the color grading in AE. In all actually, the smoke is supposed to emit from the buildings but I like the meteor idea better. I’ll post some updates here shortly and maybe even an animation.

Oh sorry m’man, i thought they were meteors :slight_smile: easy mistake when looking at the still :slight_smile:

Clouds can easily be done in AE, i’ve done a few in the past, just render out a single AB pass and use the mesh warp to animate the movement, works surprisingly well and realistic :slight_smile:

Sorry dude :slight_smile:

#764

Its ok. I forgive you lol.

Hey wildstorm,

Yes, in work in progress mode, its very hard to make some critics but before everything forgive me :slight_smile:

Well, the main problem i can see at that point is composite! Smoke Trails are far away from fitting in the scene! I can see that matte painting was handled very well but there is a lighting or color correction problem with ab smokes…

From background to foreground :

-Sun is very good and realistic for scene! Especially, glow of the sun is fitting perfect!

-Some of buildings have ligting (room lighting in theirselves) but some of them don’t! I think it’s a matter of time (wip situation)

-Smoke Trails need for more dramatic looking like some noisy smokes and fractal inner combustion like everlite said!

Thats all I can say for now, keep it coming, good job!

#766

Lol, I also thought they were meteors. :slight_smile: I think the problem there is that they’re too steep. Must be a hell of a hurricane blowing. Also, smoke like that disperses quicker, I’d say.

hey n0mad, here a screenshot.
when i wrote the last post, i missed something to mention, and this leaded me to write something not really correct :wink:
sorry for that.
but here i have a good way to do it i think.
merge the colorcorrected FG over the background, WITHOUT merging the alpha.
and then simply copy the alpha channel back into the comp.

CapitanRed , thank you very much.
You really helped me.

Hello people.
Please, tell me your meanings about my clouds.

Hello! I’ve got a quite big problem with my renders with Afterburn. Just look at the render:

http://greenheaven.pl/afterburn/render.jpg

The clouds I am trying to do are very pixelated (just as if the noise map would be too low resolution?). These are my settings:

http://greenheaven.pl/afterburn/settings1.png
http://greenheaven.pl/afterburn/settings2.png
http://greenheaven.pl/afterburn/settings3.png

I couldn’t find the problem anywhere else. It only seems to occur once every couple of scenes. I’m using MAX 8 and rendering in Default Scanline Renderer. Any clue?

Thanks in advance…
V.

Try lowering your step size to something like .2 …if you have a step size of 1 and a sphere size of 2, you’re basically going to be chopping up the volume into only 2 slices, thus it looking crappy :slight_smile:

#772

You are using smoke type for puffy clouds, switch them to fractal or turbulance,

Bigger size with the current noise size is gonna be more suitable,

Chance gain to default value : 0.5 and give more detail, lower the blur, density falloff : cubic not linear!

So those what I would do if I could have the file! To be honest, I can’t understand what have you done in the scene, clouds in the atmospheric layers?

#773

The second one looks great. The other 2 need more noise/detail. Plus, they mostly look like small little puffs instead of meshed cloud layers. Use fewer particels, and perhaps scaling the overall size, increasing the sphere radius, and adding to your noise size should help. Your second image is a good reference, and would pass as a photograph. Nice job.

Hello guys.

Is it possible to render velocity pass for AB particles?

Merry Christmas and Happy new year everyone.

Hello everyone, Greetings and Salutations!

I hope everyone is having a wonderful holiday. I hate to be a bit of a bother, but I am having trouble and could use some help. As you can see, there are strange artifacts appearing in the render.

I’m using Afterburn 3.2a with 3ds Max 2008 on an everex xt5000t (amd turion, dual processor) running vista x64. Here are my settings.




The tutorial I am attempting to follow is here:

http://www.3dtotal.com/team/Tutorials_2/afterburn/afterburn_01.asp

The scene consists of the particle flow setup, a sphere, a targeted spot and a wind force. All settings are those suggested in the tutorial.

I would be greatful if you can help me solve this problem. Merry Christmas to you and yours and I hope you all have a joyous and prosperous new year.

dnashj33,

thank you for your comment.

wncRanger,

In Pflow > PF Source > Render 01 operator - set Type to “None” .
I believe it will fix your artifacts.

#778

Ta n0mad!!! That was brilliant. I knew I was overlooking something completely simple and at two of the morning, one’s mind isn’t spot on.

Merry Christmas, all!

Thanks everyone for hints on my render too! :] Reducing the step size to 0,05 and changing the type of noise helped a lot. Thanks and Merry Christmas : )

Guys, Anyone can help me how to do motioblur with AB particles in post? I want to give motionblur in combustion using velocity chennel. But i don’t know how to export velocity pass for AB particles?

Thank you for the helps!
