Krakatoa Tutorial - Part 2

[wolfenpixels]

this was great tutorial for learning the krakatoa plugin , many thanks. Other tutorials don't explain it quite as easily.

[AkademicDesignLabs]

Followed every step, i can see particles when they render inside Max, but when I render PNG sequence, there's no visible particles. Explain please.

[spider853]

@AkademicDesignLabs I'm not sure what is the problem but maybe:

1. Your particles are black and you see in framewindow the alpha channel, so when in png there are black on black.

2. Maybe you're selecting the wrong viewport when pressing the render button. (f9 remembers the last viewport while render uses the current)

[AkademicDesignLabs]

@spider853 Spider I got it. You have to unclick "force additive mode" and add a light to your scene.

[spider853]

@AkademicDesignLabs Actually with force additive mode should render correctly, adding light its just another shading for particles.

Can you make a simple test with a particle system, and only additive mode enabled, render it to png (24bit | with alpha or without), and see if its working.

I didn't have any problems with png and additive mode.

I find it very usefull. C'mon buddy, post somethin else like that!

[spider853]

@Zudinmaverick thanks, check other tutorials ;)

Or if you have Yahoo messenger, it's better.

Just to chat not using microphone.

[spider853]

@andreirotarucatalin sorry, I'm busy now with a project, if you have some difficulties with After Effects, just search some tutorials, youtube is full of it, also there is a site videocopilot . com just have tutorials for beginners to advanced. If you have problems with this tutorial feel free to post here, I'll will answer as soon I will have some time.

[andreirotarucatalin]

Do you have skype?

I have some trouble with my scene and I can't find any specific answer on the internet.Maybe you can assist me?

[andreirotarucatalin]

I just want to render the particles from krakatoa with a nicer background. The black is to...ugly

[spider853]

@andreirotarucatalin Just add the background in post, in any video editing software, like After Effects, just render the sequence from max to PNG, and load them in AE (after effects) for example, then add your background bellow the particle layer. Render to a video file.

[andreirotarucatalin]

But he doesn't use another renderer, like vray?

Can you make a tutorial for thoose things you mentioned ?

[spider853]

@andreirotarucatalin No, Krakatoa is for rendering particles, if you want to render objects its a different story... most of what I've said are in my tutorials, Krakatoa Tips, Krakatoa Mapping, The color by age tutorial can be modified to color by velocity.. for post watch some after effects tutorials. for lighting, maybe I'll make another tutorial but there are some tutorials already on yt, just search krakatoa tutorials and you will found one, I think FumeFX Krakatoa Tut by OdiaFilm has this.

[andreirotarucatalin]

Your tutorials are amazing. Thx.

One thing i have to ask.How do i render like MatthiasmVideos?What he uses?

[spider853]

@andreirotarucatalin Actually I don't know for sure what he uses, but looks like he is doing some multipass particles (background, middle, foreground), for the middle he may use multiple groups (like different simulations cached with krakatoa and loaded with prt loader) with different shaders (color by age, by texture, by velocity, ...) without additive mode, using 1 light per emitter and some more for ambient, and using the shadow pass option for letting the light passing thru dense particles

[spider853]

@andreirotarucatalin He uses motion blur, variable depth of field (not sure, in post or in krakatoa), glow, color correction, solid background with some vignette, and its depends on what style do you want or imagine, color correction, ...

And the particles are driven procedural by a sphere that is animated by hand for the music, and they just travel thru different events for different behavior

[ultimateozz]

great tutorial! i understand krakatoa just by seeing your tutorial! many thanks! just wondering why my particle always looked transparan? and i have the same problem,i have 100 frames and it only go to 30frame and die.. any solution mate?

[ultimateozz]

@ultimateozz transparan i mean that even i add 10million particle its just the same with 500.000

[spider853]

@ultimateozz I think you don't have enough RAM

how much ram do you have?

[ultimateozz]

@spider853 solved.. i have 12GB RAM.. :) the problem is whenever the force additive mode is on,i wont have particles like smoke.. it will always go transparent.. :) thanks

[alldin]

Thank you for this great tutorial ! =)

[BakkerNils]

Great tutorial!

Thank you very much!

[ducktopia301]

VERY good tutorial

thank you very much!

[A1ZUDD1N]

anybody got links to krakatoa torrents?????

[fossoy]

great explaining tutorial, also good tips at the end. Your english is more than good enough!

[spider853]

@fossoy Thanks!

[trustwebvideo]

thanks a lot, awesome!

[WTHcoconut]

I try to make my animation 800 frames. Problem is, Particles only go to 100 frames. Where can I set Particle frame setting?

[spider853]

@WTHcoconut Make sure all the simulation (fumefx/pflow) and frame settings are to 800+ frames

first FumeFX (end frame) then FumeFX Birth (Emit Stop)

[iwantbobo]

Dear Adrian/spider853, please help. I keep receiving an error message when I render my colored smoke which reads - Unable to get channel "TextureCoord" - I figured out it happens when I choose Gradient Ramp in Magmaflow 2:14 (Plus the material editor balls/maps don't appear in the squares, it's just an empty black square. This only happens when I get to this point of your tutorial).

Please help, thank you.

[spider853]

@iwantbobo Hi, The problem is that you didn't define the texture coords channel before the color channel, you see in the tutorial that I'm doing the Texture Coords output, and then (on the same global object) "KrakatoaGlobalOverride" I add the Color Channel. If you're defining in the same order then the problem might be that you create a new Global Channel, just make sure you've selected the one you created earlier and from modifiers list add the KCM modificator

[iwantbobo]

@spider853 Sorry to bother you again. But I've defined the texture coords channel before the color channel and still the same problem occurs. I've followed your instructions implicitly, maybe I just plain stupid, but if you have any other suggestion that would help me out I'd greatly appreciate it.

Thanks.

[doktorgriff]

@iwantbobo I had exactly the same problem, fixed it by just dragging the KCM_Color modifier down in the stack below the KCM_TextureCoord. Hope this works for you. :) I don't see the textures either, think we are using a slightly different version of it.

[wharpland]

Nice job ! Excellent tutorial, Thank you

[punjedi]

Your English was more than enough for me to follow along. Excellent tutorial, Thank You!!

[FJoannot]

just "THE" best tutorial !!! thank you it's amazingly powerfull.

[spider853]

@FJoannot Thanks :)

[chillsoft]

@spider853 It really is one of the best tutorials I have ever seen, free och tutorials you pay for, this is the best one for Krakatoa. You explain everything very good and make it understandable! :)

[bbadboy07]

That was a very good tutorial ! I really liked that you also explained very well what you were doing, other tutorials are just "do this and do that" you were very clear and I understood from your english too ! Nice Job :) !

[spider853]

@bbadboy07 Thanks, I'm glad you like it !

[kingsquex]

very good,powerful tutorial
