Looks like Aerodynamics has improved greatly since his last animation.

The wideness of the Kujira models (which is what keeps me returning to his animations, despite the masochistic aspects) probably comes from the Tso2Pmx converter. I made a couple of thick models of my own using that, but unfortunately, they appear white in MMD (along with others I downloaded from DeviantArt, so at least it's not a problem with the files themselves.) I might just need a different version of MMD.

Are you planning on doing Animations?

I can't stand the 3D Custom Girl artstyle. Every character looks like the same girl in a different wig. But Kujira makes it work, somehow. Probably the camera work.

I might. It's not really a priority for me, though, and I'm not sure what to do about the "white glitch".

Alright, update. I tried a bunch of stuff out, figures a bunch of stuff out, and now have a moving model with a customized Jetsmoke effect coming from her waist. However...whichever way I turn the camera, the model ends up in front of the "smoke," defeating the entire point! Any help would be appreciated; it's really the only thing standing in the way of me actually making animations aside from time.

I had the same problem, for a long time. Go to Background -> Accessories Edit, and change the 1 in the text box to a zero.

Also, since you're going to want the gas to appear and disappear at the right times: do this by changing the Size of the accessory in MMD. This makes it spawn and dissipate correctly.

Thanks very much for that. I was able to iron things out a bit and made an animation. I'm a bit hesitant about posting it, as it didn't take very long and I still need to get better with the gas effect, but here it is: http://1drv.ms/1Iy1cUD I'd encourage anyone else who's interested in making animations to give it a shot; while it might take a while to master, it's much easier than I thought to get started.

By adjusting the parameters, you can make quite decent smoke effect.
Usually I set the Tr = 0.2~0.3. That makes the fart cloud realistic.

Other parameters can be found in the .fx file. Listed below is one typical set of parameters I use.

float3 ParticleColor = {0.8, 0.8, 0}; // RGB
float ParticleSize = 0.2;
float ParticleSpeedMin = 15;
float ParticleSpeedMax = 30;
float ParticleInitPos = 0.0; //Don't change this.
float ParticleLife = 6; //In seconds
float ParticleDecrement = 0.0; // (0~1)When the smoke starts to dissipate
float ParticleContrast = 0.2; // (0~1)The shade gives the smoke the 3D feeling
float ParticleShadeDiffusion = 1.0; // No idea
float ParticleOccur = 3; // Particles geneartion rate
float DiffusionAngle = 25;
float SpeedDampCoef = 4; // The rate of decceleration of the particles
float SpeedFixCoef = 0.05; // The end speed of the particles
float Scale = 1.0; // Don't need to change this, change scale in MMD


Also you can find one line in the main file:
float scale = 4.0f * sqrt(etime) + 2.0f;
4.0 is the particle size expanstion rate coefficient, and you can change it into any number you want. The particles expand with proportion to t^-(1/2). It can also be changed into other formula. 2.0 is the initial scale, you don't need to change it here.

@vitun_kusipaa Just incase you plan to make more I created a folder awhile back as a source of sounds for anymore who needs it.

This is nice. Really need them. Many thanks!
Can you upload them in a packed form? It's a pain in the ass to download one by one...

I gotta go now but when I get home I'll see what I can do.
