No promises of finishing :)

Not much to show, but this is my first render test. Needs a lot of work still.

I'm booked solid for the rest of the week. That will leave me the next week to get started and finish by the 15'th. lol, last minute. That's how things are done in 3D. So at least I'm doing something right.

I'm still learning more about fluids, but I'm starting to refine the shape of the mushroom cloud.

I'm not sure what I can say about my progress so far. My job keeps me very busy but I really wanted to finish something for this challenge. Always wanted to learn how to do a nuke. So the value of the "how to" part has been great.

Anyway, this is my progress so far. It's only a test render and I'll be posting more as I bring together other elements of the nuke.

Ok, that's all I have time for today. I only had a few hours today to refine the look, but I think I'm getting closer to something I can work with.

Here's some samples. The lighting still needs some more work.

Hmm, this is interesting. at first it looked more like maya fluids, now its looking more like fumefx.. which one is it? lol

yea it's a pain to get that initial shape but once you do it gets easier.
the one thing i noticed is that you still have fuel pumping into your system, I eventually used geometry for better control but I since have been testing other ways and I noticed birthing everything over like 3 frames and then killing it just as fast works pretty well.

Good luck man, I hope you get something finished. the more entries the better.

Very nice shape.

If I may offer a crit, I might scale it up just a tad and move it in line way back to where that mountian on the right dives into the ground, the shot is a bit to close. It is a really nice backplate, it is just that road in the foreground really drives your scene scale.

The burn in the very first test you did is sweet ;)

@tool2heal - thanks, I'm not using either of those. For this I'm learning Houdini for the first time so my progress has been very slow, and we don't have Houdini here so I have to wait until I can get access to it. I'm thinking of joining Digital Tutors to learn more as the manual is cryptic. I keep pumping fuel into the cloud at the base to maintain the shaft, but I'm hoping to come up with a new design this week to break it into three different forms.

@JohnnyRandom - thanks, I think I will move it back a bit to show more. I hope to render it in HD if I have time. When you say scale it up. Do you mean scale the size or the sim detail?

Yea I can see what johnny is saying, he means move the fluid grid further from the camera with that road in your backplate right now it looks like your explosion is only about 100-200 feet from the camera. That's what I was discussing with him in his thread, the idea of the further you move the grid from the camera the larger the grid has to get. therefore if you want your explosion 1mile from the camera, you need a huge grid. a grid that with my computer is impossible to have.

Same thing with a grid for a shockwave I mean if your explosion is a mile away and you want your shockwave to blow by the camera, that means your grid needs to be 1 mile square? Thats just not happening with my setup and if I even try my spacing needs to be way up there like it was in my entry at 4.

Wow houdini huh, nice job so far man, I can never wrap my head around those damn node based programs, that's why I'm still using pflow instead of thinking particles :/

Exactly, BUT you also do NOT have to use such a small voxel either. You have to have a small enough voxel to get good detail at distance yet a big enough voxel to maximize efficiency, it is a straight up balancing act.

I am not exactly how Houdini fluids work other than they are voxel based and you have the option to upres (that is a sexy feature) Good on ya for picking it up, I'd like to pick up and play with the apprentice HD sometime :) Looks fun!

Nodes are good for you tool2heal :D

Some render tests and an animation preview. When I look at these I see a lot of things wrong and in need of improvements, but it's been a very slow process as half the time I can't get Houdini to do what I want and the other half it just stops cooperating. So adding the shockwave on the ground took longer then expected and didn't turn out the way I wanted. So more revisions are required if I can find the time to make them.

So I had some problems this morning and lost two days worth of work on this thing, which resulted in me giving up on the challenge. After cooling off I reverted to an older backup and pressed on.

Not much has changed except that I'm trying to refine the look in post. Wish I had more time to tweak the simulation some more, but I think I'm running out of time. :)

These are low res simulations.

hey man good job, especially with learning a new program. if anything be happy that your progressing with your talents. good luck.

Good to see your giving Houdini a whirl, your first image gives it away !. Not sure how much help your allowed to accept with challenges and such but you should get yourself over to odforce and the sidefx forum. I know over at odforce nuclear explosions have been done with lots of scene files available to dig into with lots of learning videos over on the sidefx site.

As a tip remember you dont have to sim everything to get good looking nuclear explosions. Animating geometry that's turned into a volume and then adding a noise into the volume work very well.

@tool2heal - thanks, a friend has been bugging me to try Houdini for years, and I finally gave in and happy that I did. Choosing to do a nuke as your first exposure to new software isn't recommended. That was a tough learning curve. ;) Just three weeks ago I didn't know what a node was.

@mr Rob - thanks, I saw some of the Nukes done at odforce. The work done by the user chumbuk is really impressive and he's shared his HIP files on the forums. He did an ocean based nuke here at YouTube (http://www.youtube.com/watch?v=8DkatI-GKu4&feature=related), and posted the source file here at odforce (http://forums.odforce.net/index.php?/topic/8897-underwater-atomic-explosion/page__fromsearch__1). Great stuff, renders very quick, and I have no clue how he did it. lol, I have much to learn about VEX shaders.

I think I will be done today. Sadly, I ran out of time and will be posting the low res version with the original nuke simulation. I did rig and build a better nuke but there's no way I could run the sim, up res and render the passes. I hope we do a nuke challenge again. I'd love to give this another try.

tell me about it, since I finished on time I thought, hmm. why not try and make a second entry in the extra week we had, and it's slowly already turning out better then my entry. well at least it's something to work on and refine and then maybe stick in a reel or something, I will probably bring it to the fumefx thread and tell some of my techniques and stuff.

Good luck with the challenge man.

It was nice to have the option of an extra week I only wish I could have utilized the time as well.

Oh well, it has been good to see other peoples projects progress :)

Well guys, I'm done. Not sure it turned out that great, and I might have gotten a little carried away with the post.

There is a mp4 link on the other thread.

Check out this compositing setup in Houdini. I've used AfterEffects but I really like node based compositing a lot more. I've never used Nuke but if it's anything like this I'm sure I should give it a try. (right click and select view image to zoom in).
