View Full Version : Mini Gun
02 February 2005, 12:14 AM
Hi there, I have started a similar post in the 3D Stills work in progress but realised that it might have been in the wrong section, anyone know how to move threads? If not then I will start it up here. This is just a little animation I have been working on. Here is my mini gun model.
The idea behind this is that it folds out from underneath some footage of my car, I also have some rocket arms that come out from the bonnet. Here is a before and after of the scene.
I have matched a model of my mini to the footage pretty accurately. You can check out the test animation here.
Anyone got any ideas for a muzzle flare?? I just have a flat plane at the moment, but I want something decent to show up in the car body. The sound of the mini gun has been taken out so its a smaller download. But I have hte brightness of the light wired to the amplitude of the wave file, I don't think there is enough contrast in the scene myself. There is one other light on the roof to simulate the fluro light that exists. In the animation I don't have shadows on the car body which definitely needs to be done. Also working on some empty bullet shells to fly out of the gun...

Just made a bullet shell system to eject the empty cartridges from the gun. Similar to the light I have an object hooked to the waveform of my sound and then a small pflow script that analyses the difference between the objects position to decide whether to eject a casing or not. Needs a little tweek on the values and because it is kinda reacting to the sound when i do the final composite will shift it back so that it syncs up a little better.
BTW...Sound is compressed heavily
Let me know if you can't see these videos, I can play them off my hard drive but can't over the internet!! Friends can see these though..

First time i saw it i was sayin to myself "that guy should put some plfow setup for the empty cartridges" :D
Dude, you should animate a rotation for the minigun and animate the fire blast!
nyways its a cool start, makes me think of rock n roll racing :)

http://users.tpg.com.au/walkaz/test/shells.jpgCan someone tell me why this would render a blank screen. It is a plfow emitter instancing a fired bullet shell in my scene, the instance is visible (dunno if this matters anyway) and renders nicely, but when my pflow emits the particles they render as nothing. Why? You can see from my screen shot that the geometry exists.....?? The only reason I can think of is that my particles are being birthed from a script that analyses my bullet shells wave file to tell when to add a particle. And it does this by analysing the value from the previous frame.....so does this geometry not really exist at render time?? Ideas? Thanks.

I am still having trouble rendering out my shells......when I do a preview animation from frames 0 - 220 it renders the bullet shells no worries, but when i do a production render, they aren't there and when i do get them to render there are way too many shells compared to what I am getting in the viewport....i have a birth script creating the particles......might try the maxscript channel...cheers!! :)

figured out the shell rendering, still is weird but at least you can see them!!
Check out the basic render, just gotta add the muzzle flare and bullet trails. too many bullet shells?

I didn't know mini guns didn't have muzzle flashes, but too late I made one and put my animatino together with some sound effects.....I am happy with what I have learnt on this so far so I think it may be time to move onto something else!! :) I have noticed that I have been replying alot too myself with this thread so if you are reading this, get a life!! ;) But while you are here check it out.

Nice stuff, too bad about the muzzle flash. The only thing I would say is that at the moment the shells are coming out in a perfect stream, like a fountain. They need a bit more randomness in the spread. I am also not sure if it is possible to randomise their rotation a bit either (as I am sure they would not all follow exactly the same trajectory, speed, rotation in real life).
You need to hold of that old DVD "Hot Chicks with Guns" or something like that. It was all these chicks in bikinis shooting machine guns!!! lol Each chick had a slo-mo section so you could watch bits . . . errr move about. Would be great for checking out the shells (Sheesh, what a nerd).

what about the missile launcher !!
Yeah but some randomness in the speed of the cartridges and some divergence for a more random flow.

Here is a new render of the shells, what do you think??? Its not hard to take the muzzle flash out, its all setup in combustion as separate layers. I reckon it would be a bit boring without it though.

That looks tonnes better. As for the muzzle flash, I agree. Who cares about reality if it makes the scene look better? The general populance would think there should be a flash, in my opinion. The only people who will care will be military boffins, and let's face it, they don't count :eek:

yo, did a re composite of the new shells, adding a subtle shell hitting ground sound effect. Thanks for your comments
