ART - Variable Ammo Repeater Cannon


Exo2000

Recommended Posts

 

 

Revel in it's shinyness and uncompletedness, for now I presenteth a WIP render of the craft cannon! Well, more of an autocannon. It's not exactly "to scale" and could easily be shrunk/resized as needed.

 

And a little.. CTD, to fit the actual design;

 

X-Corps Technology Report, DR-15 "Renegade" Craft Autocannon;

 

Munitions; Depleted Uranium-tipped high-cal armour-piercing high-explosive rounds.

 

The DR-15, or as it's better known, "Renegade", Man-Portable Autocannon, has proven to be especially effect against many targets. Instead of being a subtle two-handed, man-carried dealie, the Renegade was redesigned specifically for X-Corps. Using a specially designed body unit and feeder, the Renegade provides heavy automatic chaingun fire with it's six rotary barrels and constant ammo feed. It's fire rate is fully continous, ie, automatic, and rips weak organic targets apart in seconds. This is especially lethal against earth aircraft and organic objects, and field tests prove that it is, currently, useless against UFOs. The same cannot be said for the alien life forms - suffice to say, if the soldier can hold it still long enough, any aliens within range (and any civilians) are going to be plastered all over the opposite wall and floors.

 

X-Corps Soldier Interview; Gunther Heinrich

 

"At first, when I saw the Renegade, I thought "hey, what a piece of oversized junk!". That all changed when we saw the first alien in that combat. Sure, firing the damn thing nearly took my arm off, but hey, what was left of the bugger was plastered over a 6ft area on the wall opposite."

 

Field "tests" have shown that, whilst not useless, the Renegade inflicts low damage against the UFOs. It is, however, an effecient craft backup, should it run out of missiles.

 

EDIT: 2217 polys, without being tidied up. The actual amount for that screenshot is about 4434, as there are two on it. A lot of polys could easily be removed, such as ones buried/hidden in other parts of the model. Doing that could maybe drop it by anywhere from 100 to 400, I have -no- idea.

we already have a craft cannon, but this would be excelent for an auto cannon. Just make it more carryable.

 

Also, don't worry about the polies. Optimizing is ok, of course, but you can unse up to 10.000 polys.

woa... if thats unfinished... if you continue like that it will barley need a texture... :D

Someone update the damn art assets list!

 

I'll work on transforming it into a carried autocannon dealie.

 

EDIT: Tada!

 

 

Took off two of the coolers, added two handlebars and put a thingie that looks a bit like an ammobox in the place of two of the coolers.

 

EDIT2: Down to 1651 polys.

yes, it's about time :P

 

the model: The previus looked waay better, sorry but those handles are lowpoly, ugly, and doesn't fit in. What program do you use?

 

Revert to the first one - keep the coolers on both sides, gives a nice effect. And as i said before, don't worry about polys.

@ mikker;

 

I use a japanese program called DoGA, it's nigh on impossible to find an english download for it now and it's far too large for me to host.

 

If what I know is correct, it should be possible to save my models as VRML/.WML files, which can be read with Blender then fed through into a format one of the other big editors (Max, etc.) can use. If not, I'll just have to move over to the CTD dept. :P

 

The handles would, most likely, have to be done manually (ie, with something that's more complex), DoGA just isn't precise enough to do them. You assemble objects out of preset parts, and resize them and so on. As such, you can only really work with the parts you get, but it's not all that hard to find a few extras.

 

EDIT: Et voila.

 

 

Handles swapped for new ones and made a bit bumpier. Firing stud added to the overhanging handle, on the end. It's not too visible without skinning.

 

EDIT2: Updated the CT in the first post to reflect that it's man-carried, not vech mounted.

 

Nice little reference for ammo;

On that chart, I suspect this baby will be hurling 4-6cm (40-60mm) slugs. Carnage. :)

now it's better, good job! My suggestion is that you make it longer and more sleek, but still having the heavy look.

I'll need a few pointers there then, this is one of my first models of an actual weapon. I have a few aircraft and "mecha" models, too, but they tend to be very similar.

Had a shot at doing it without pointers. The barrels are a good 4th longer than before, the main body a 3rd, two more vents added, and an ammofeeder and box storage added underneath. Fire-button was extended out a little.

Exo2000: While you have made a nice model, please abide by the proper guidelines for assignmnet and submission of art requests. If we do not follow a system we will end up with anarchy and no real work will be accomplished.

 

The art asset list has been superceeded by a task based structure on bugs.projectxenocide.com and doccumentation on workflow guidelines can be found at docs.projectxenocide.com. All of this information was in a pinned topic named "art department guides:new members read" at the top of this forum.

 

Thanks,

When I get my email fixed I'll be able to check the bugs list. Until then, I can polish up the model. :Coffee:

 

If anyone could get me some reference images of chainguns, preferably carried by infantry, I would be much obliged. So far, the model has had no references whatsoever, except a mental photo of the craft cannon, which it has long since strayed from.

 

EDIT:

 

 

Here it is, a reference of how to carry it, as carried by one of my standard issue robots with extra-large hands. The gun itself isn't quite that big, of course, but it's a good pose-reference.

heh, we could save up some animations if we put the handles for the heavy laser / auto cannon in the same place :)

That was my idea, hence why the handles changed to the position they're in now. :P

Added an alternate mode of carrying, an ammobox, switched to the old vents (preferred them over the others) and that's about it. Oh, added case-ejection vents on either side. :)

The only thing with it i don't like, is the huge balls. It makes it look much worse, almost comical, IMO.

K. They're just there to show how it would be held. :P

Isn't it looking too heavy? I mean for a way of handling which that hands show. I doubt any human being would carry such cannon easily in front of him. Arm muscles won't hold on too long in that position holding such heavy cannon. Try holding that way your computer chair or something heavier, I guarantee that you won't stand like that for too long. That type of cannon is hanged on stripe or deployed statically on ground before firing. Have you watched Predator 1 or Terminator 2? If yes then you'll know what I mean.

 

Or maybe a smartgun-like handling system (Aliens 2)? But it will require new character animation.

 

Edit: the closer to vertical axis of human body heavy load is, the easier human can carry it. Which means that it's easier to carry heavy things close to human body. Have you ever carried backpack in hand having your arm straight in front of you?

The auto cannon should be pritty much like a minigun....

 

http://www.montysminiguns.com/6mmpromopic.jpg

 

had a go at illustrating how it should be held for the sake of showing off my mighty 3d skills...

Update;

 

http://img215.echo.cx/img215/3171/acprogress0xt.th.jpg

 

Added placeholder gradation texture to break up the shape so the parts of it are more visible.

 

Should be ready to ship to another platform for final tweaks (any last touches of detail, and clearing up unused polys) and then texturing. :D

I don't think it really needs the vents. If it's held as in GDD's diagram, one side of it will be completely obscured by the wielder's body. :P

Here she is, all that needs to be done now is optimisation. It'll need porting through another program before it gets to 3dsMax. I should be able to port it through Blender. If I can't do that, someone will need to find a plugin or somesuch that converts from .WML to whatever the 3ds format is.

 

 

 

EDIT: My Blender doesn't want to import it. Arse. Pardon my french.

You should try and space the barrels a little farther apart, because with that things turn rate(small circle) it would fire so fast no human could handle it...

An RPM is an RPM, no matter how large the radius of the circle is.

 

No human could handle anything like a rotary barreled cannon EVER. The force of a rotary barreled rifle calibre gun (m134) is enough to life a man (and the ammo, mentioned below, but not the battery) into the air and fly him around like a bullet powered rocket. Not to mention that 2000 rounds of this ammo would weight 50 kgs (110 lbs) but would last for no longer than 20 seconds of fire.

 

I think that the barrel assembly radius is probably the least of the worries of the firer.

yeah, i always figured that the autocannon would fire pretty slow, like fire 3 rounds in 2 seconds... sort of like firing three grenades from an m203... that's how i figured it... and that's why the original autocannon was so big, because it fired relatively slowly... and the bigger the diameter of teh barrels, the slower it looks like it would spin. a Bigger diameter looks better spinning slowly

If that is the case then what is the point of having multiple barrels at all? That's a lot of wasted weight to have a multiple barrel assembly and a motor to turn it if it has a lower rate of fire than a semiautomatic pistol. Even very fast firing machineguns like the m249 (1000 rounds per minute) need only one barrel.

Because it looks spiffy? :D

 

Plus I'm not as good at single-barrel assemblies. A multi-barrel assembly like that one will be more easily recognised by gamers, as it's a more distinctive design. It "says" "autocannon", not "heavymachinegun".

 

Plus, I was thinking about it;

 

The old X-COM 1 Heavy Cannons had a bore much, much larger than that of any tank. I think a lot of the X-COM 1 heavy weapons were out of proportion.

To give you an idea of what a gatling gun (these images/models that have been posted so far are of a gatling gun, not an auto cannon, ie x-com 1) can do, Here's the AN/GAU-8 from the A-10 Thunderbolt II.

 

http://www.mindfully.org/Nucs/2003/Rokke-Depleted-Uranium-DU21apr03f.jpg

 

Two rates of fire, 2,100 r.p.m and 4,200 r.p.m.

 

the forces created by prolonged firing of the weapon is almost enough to stop the aircraft in mid-flight.

 

Therefore, if you want to use a gatling-style weapon for the autocannon, just take creative license and make it the way you want it. There's always Metal Storm, if you wanna go a little bit advanced :D

 

http://www.metalstorm.com/

 

electronic balistics

 

http://www.metalstorm.com/05_graphics/large_images/area_denial/area019.jpg

 

That's a gun... The prototype can theoretically fire arround a milion rounds a second. You could take the same idea and build an autocannon similar to X-Com out of it.

 

Anyway, What I'm trying to say is that it's a game - make it look beliveable and you can have some guy dual wielding gauss rifles, firing from the hips like Arnold in Eraser

All of the weapons in xenocide are getting a face lift, and none of the names will be the same, so no matter what the device looks like, it will not be named 'autocannon.'

The way it works is to have multiple rounds lined up in the barrel, donkey to nose. I can't really see anything aesthetically pleasing about a box shaped tube.

 

A more contemporary and realistic bases for the 'autocannon' would be the oicw grenade launcher component.

I'm not talking about names, I'm talking about what the gun actually says without saying anything. Something like a SAW is obviously a Heavy Machinegun, but something like the chaingun/minigun there is more obviously an Autocannon, even if it goes by a different name, it will still obviously be the equivalent of the old autocannon.

 

Is the Heavy Cannon anywhere around here, or has it been ditched, or was it never started?

The concept of the autocannon can say whatever you want it to say, because it is your work of art. Let us not confuse what we are doing with what xcom did (artistically). If your concept speaks 'autocannon' to you, that's well and good. The minimum gameplay requirements that we as artists need to fulfill for this weapon are that it must be a direct fire weapon that shoots 3 shots per round, is magazine fed, and launches small explosive projectiles very short ranges (in comparison to a real equivalent). Additional to that, there are requirements in the style guide. Outside of those requirements, there is nothing that we need burden ourselves with.

 

As for what autocannons are, they are cannons that load themselves. Putting 5 extra barrels on a rifle calibre machinegun does not make it a cannon all of a sudden. Cannon rounds are a clear class of munition that boarders with rifle calibre rounds at about the half inch mark. They are propelled under high pressure from a breach- which seperates them from rocket propelled grenades, rifle grenades or low pressure grenades (such as those launched by the m203). Clearly, no human would be able to control an 'autocannon' realistically. Interestingly enough (to myself, anyway), the autocannon on the M2 BFVS is not even particularly fast firing. The fact that the cannon loads itself is enough to make it an autocannon.

 

The concept derived from the heavy cannon is an anti-material munitions delivery system based on the M82a2 .50 calibre bullpup and the Croatian hand-held 20mm cannon. The thread is available here.

 

Also, finding the thread was as easy as skimming down the page here. In the future, could you please use the search function or give the forums a once over before you send someone else to go find them? Thanks.

I pulled off three of the barrels and beefed up the remaining 3 to make it look a little more dangerous;

 

http://img298.echo.cx/img298/9701/autocannoncannon8rr.th.jpg

 

Also added the side-loading clip for ammo.

 

Note; I'm figuring each time it fired, the barrels would rotate and click the next one into place, like a back to front revolver.

 

Example;

 

Barrel 1 in position

User Fires

Barrel 2 now in position

User Fires

Barrel 3 now in position

User Fires

Barrel 1 now in position

 

etc.

That thing looks like it can do alot of damage, and has a huge recoil... Whats up with the texture?

Sorry, just a placeholder on my program that I forgot to remove. :D

 

~~

 

And most weapons have recoil. I imagine the Heavy Cannon is going to have recoil through the roof. ;)

 

Note; and yes, it's supposed to do a lot of damage. It's an autocannon firing HE/IN/AP rounds, (High Explosive, Incendiary and Armour Piercing respectively) so I'd say it's gonna do quite a bit of damage. :laugh:

Hey exo, it looks good but I have one question, I know you use Doga (or you did last time I heard), can you export into 3dS with it? because Vaaish said final models must be in .MAX to be used, I'm updating the gallery of the main site and I want to know if this model is able to be used in the future :)

Here's an autocannon concept. It's based on several different concepts for the xm25- which is the real life equivalent. It's a 25 mm low velocity cannon/grenade launcher/sniper system. The concept (the xm25 weapon system concept) is sort of outside of conventional weapon system concepts, but it is essentially a very accurate, semi automatic grenade launcher with a computerized site and programmable airburst ammunition.

I really like where this concept is heading as it looks quite advanced and creible. Lets wait for Vaaish to know if it compatible with the general art vision.

I've been thinking about this one and I'm not too fond of how the stock is attached at the back and how the site is attached. Another area thas bothering me is that angled line below the thumb hole, how about making the pistol grip a little more separate instead of the straight line going back. I like the overall feel and utility of the weapon but lets refile the aesthetcis on those portions a bit more.

 

Possibly integrate the site more closly to the body and not as raised where it joins the barrel.
