Volumetric Explosions by Morgantao

I just saw that preview. I must say I kinda like the flow of the smoke, it looks like a spinning motion.
If you want I will still check the noise for other flowing motion types.

Here's an animation with the smoke flowing from the center out:

And here's the first one again (Center out) without the last frame hanging....

How about I upload it and we both tweak it

Do you have any idea what you kind of flow\motion you want in the first half?

Explosion Frame Generator_WIP 3.ffxml

Here are a couple of tweaks I made.
The first one is a little more subtle:

Well, here's one that's in between the first and second.
BTW, the only thing changed between the animations is just the setting on the Smoke Upward Flow slider.
First one is 100, second is 0. Here it is with 50:

One last example,same settings as third one on animation side, other sliders are randomized.
Also framerate is changed.

Why are you working with only 64x64px canvas? With todays mega game resolutions that seems pretty tiny to me. Then again I know next to nothing about game particle systems.

I would love to see a demo of what you do with those, both in Forsaken and Unity. And any other use you make of it.

BTW, what do you do for a living?

Here is my new iteration. Mainly I changed your offset for the noise by a scale.

I am using 64x64 mainly for the speed. But for mobile devices games you would not go for anything bigger anyway. This may answer the question, I am a game artist and iOS game developer.

About Forsaken stuff, it's just a hobby.

Yep, I agree. I am trying to find a solution, the problem is that flow at the beginning means too much flow at the end.

Wow that is totally cool! O.O

Cool.
Oh, and about that atlas generator, if I have a 32 frame animation, does it just take every n'th frame, to get the right ammount of frames (Like every 2nd frame for a 16 frame animation)?

Hmmm...
Do you have an idea on how to have all the different frames rendered on the same image?
The only way I can think of right now is to duplicate the filter 16 times, once per frame, and that would make it dead slow and morbidly bloated.

Why not just use Sjeiti's ffbatch (Read about it here: http://www.filterforge.com/forum/read...5&TID=6133).

Ok. This is how the filter would be perfect:

1. The fire behaves like in your last iteration with this setup (attached).
The fire evolves till the frame 9 (out of 17) the right way.

2. Then, I would go back to my last iteration and use the way the smoke fades out, but fades out too fast, and the last frames is nearly invisible. Not a problem since we have frame control, and we can avoid that in the atlas making.

I hope this is clear enough mate.

The offset thing will work with many other particles FX, magic stuff and "special" weapons, even more if the ccolors for the fire can be changed, and playing with the noise tipes will bring even cooler FX sprites. But for the explosion the noise scale may be more suitable since it grows from the center. I am attaching the new iteration in case you have a new great idea Explosion Frame Generator_WIP 4.ffxml

This is my last iteration. I didn't mean my iteration renders faster, in fact, it's your tweaks what made it render faster.

Let's make sure I got everything right: * The file you attached on your last post (WIP_5a), that's the setup you want for the first 9 frames. * You want a total of 16 frames. * You want frames 10 to to be from your last iteration Right?

* Yes
* Well, I want 16 but someone (or me) may want 24 or 15 some day. The idea is to have a "standard" one but you can tweak if you edit the filter. What I mean is that we are not looking for a fixed frame filter that may not work if you change the framerate. For our approach, 16 frames is OK.
* Yes, the "Explosion Frame Generator_WIP 4.ffxml".

sounds great, thank you

I didn't have much time to work on this last week, but I haven't forgot about it
I hope to work on it later tonight.

I'm not sure there's a smart way to make the atlas in FF.
The only way I can think of is to use the animation tool, which is actuallywasy to use, and I'm pretty sure will be about 15868765 times fater than using the filter in the non smart way.

Oh man, take it easy
Fr om my POV you should not spend so much time on the filter. If we do this the non smart way, we don't need to merge the 2 halves.
I would suggest to publish the filter as it is (which is great), and then the atlas maker wh ere we can control the noises frame by frame.
You will need a huge computer to render that at high res but no high res render for an explosion atlas is needed.

Hello Morgantao.
I am back to this filter, because I am going to use it for the project I talked about some posts ago.
I am using my last iteration, I was wondering if I (we) can submit it as a filter for the community.

Dactilar, I suppose we could upload this filter to the library, but I'm not sure if that last itteration is the best for the library.
While that itteration works best for the project you're working on, the filters in the library in general should provide the user with the greatest amount of customization, and I think one of the other versions had more variation in it (more controls).
It's been a while now so I don't remember which version did what, but there was one that allowed for more control than the others.

CC, I guess I can try to add some more realism to the filter, but that would have to wait for a later update. I have a feeling it won't be an easy fix

I'd love to see a manga explosion version

Me too
unfortunatly my manga skils are limited to watching an English dubbed movie here and there....

Thanks!
