Introduction

While Halo 4’s Forge Objects within the Structure Pallet may be based off Halo: Reach’s alliteration, they are not identical. Differences from Reach to 4 include not only new textures, but many objects have noticeable changes as well. This thread, while it may seem late, will provide Forgers the approximate amount of space (not necessarily volume) that each object covers up.

Hopefully, after reading this, effectively drawing out your maps prior to Forging them will become a hell of a lot easier for you.

ITT, each Forge Object is measured by Blocks (abbriviated as Blc). A block, in game, is ten intervals in the coordinate plane (the size of a Block 1x1). However, it must be noted that not all objects can be measured by a whole number of blocks, but will be represented with decimal places. As an example, a Block 1x1, Flat is 1 bloc long, 1 block wide, and 0.20 blocks tall.

The format for measuring each side of an object is the length (the longest side) times the width (the shorter side) times the height. This will be displayed as the following: L x W x H

And with all of that being said, may the list begin…

While at first, this thread was only designed to give Forgers the ablility to map out Structure pieces, I soon realized that making a map goes far beyond bricks and blocks. Whether it is knowing how far a mancannon will launch a player, or how many shield pieces it will take to plug up that gap, there are far more details to be noted.

In the following lists, the format is a bit different. The measurements for the Mancannons work differently from the measurements of the others. Instead of showing how large the object is itself, the following list shows how far and how high the Man Cannon will launch the player. This is displayed as Horizontal Distance x Vertical Distance.
Mancannons:
- Mancannon Light: 27.5 x 3.2
- Mancannon: 37.5 x 5.2
- Mancannon Heavy: 57.5 x 7.5

Below you will see the measurements of Halo 4’s Gravity Lifts, but those follow differences in measurement as well. Due to the fact that Gravity Lifts don’t send the player in any horizontal distance, the maximum height a player can achieve (with player gravity set at 100%) when walking onto the Grav-lift, NOT jumping or falling onto it.

Gravity Lifts:
- Gravity Lift: 6.5
- Gravity Lift Heavy: 7.5

Additional Information

  • One Block is equivalent to 3.1 meters in the real world (credit to M0aHerder for finding this out)

Wow, this thread was extremely helpful.

Also, looking at the map-specific objects, I’ve noticed that the objects from Impact and Erosion are highly inconsistent with each other. At first, I thought that it may have been that you had miss-measured them, but after trying to make a map from Station objects and finding that it was impossible, it appears that that is all but completely true.

It’s completely ridiculous how 343/Certain Affinity couldn’t make an effective Forge pallet. Hopefully they’ll do better with 5.

I did some calculations a while ago and found that one Blk is about 3.1 meters, which is useful for anyone recreating something in-game.

I’ll note that one.

I just came across this thread. I gotta say, Andy, you did a fantastic job. Its really helpful. Thanks for posting it.

You’re welcome.

Also, after discovering that unlike Halo Reach, Halo 4 allows the player to view the object shape dimensions for all objects, perhaps I should remeasure all of the objects to clean up any potential mistakes. The current measurements were gathered by me taking a Block 1x1 and seeing how many I can line up among the edge of the object which resulted in me having to make many visual estimations when objects left the realms of whole numbers.

If I remeasure with object shape dimensions, I can get a completely accurate measure. However, I’d also have to get a new copy of Halo 4… Ring-stratches destroyed all of them.

Update:

Upon request of undisclosed individuals, I’ve added the vertical and horizontal distances that Mancannons will send the player, and I’ve added how high a Gravity Lift will send a player.

If anyone would like me to provide any measurements for things, feel free to post here or PM me.
