Most of us are busy learning the new Controls, but the real hustle comes with converting the old units from past Forge iterations into the new ones for Halo 5. In the past, we have used World Units for measurements. World Units are equivalent to the height of the Spartan, which is 8 feet. 1 World Unit (WU) on the Coordinate Grid is also 8 feet. Halo 5 however uses Feet to help transition Forgers into Professional Level Design, where Software Development Kits (SDK) such as Maya may also use Feet or Meters. Feet were chosen instead of Meters to avoid Decimals and Fractions. PROBLEM: We want to spawn a Block 2x4, which is 2WUs x 4WUs x 1WU (Length x Width x Height) Let Halo Reach, Halo 4 and Halo 2A's Units = xWU, where x is the total value of WUs* Let Halo 5 Units = Y, where Y is the value represented in Feet *note: scale between games is not exact. FORMULA: xWU = Y SOLVE for 2WUs Y = 2(WU) Y = 2(8) Y = 16 SOLVE For 4WUs Y = 4(WU) Y = 4(8) Y = 32 CONVERTING HEIGHT in WUs to HEIGHT in FEET Normal: 1WU = 8 feet Short: 1/2WU = 4 feet Flat: 1/4WU = 2 feet Therefore, our 2x4 block is 16' x 32' x 8' SHORTHAND** (WORLD UNITS = FEET) FLAT = 2' SHORT = 4' 1 = 8' 2 = 16' 3 = 24' 4 = 32' 5 = 40' 6 = 48' 7 = 56' 8 = 64' 9 = 72' 10 = 80' 12 = 96' 16 = 128' 32 = 256' **note: some sizes may not be available in all categories COMMON PIECES FROM HALO 2 ANNIVERSARY*** (LENGTH x WIDTH x HEIGHT) Block 1 x 1, Flat = 8' x 8' x 2' Block 1 x 1, Short = 8' x 8' x 4' Block 1 x 1 = 8' x 8' x 8' Block 1 x 1 Tall = 8' x 4' x 24' Block 2 x 1, Flat = 16' x 8' x 2' Block 2 x 2, Flat = 16' x 16' x 2' Block 2 x 2, Short = 16' x 16' x 4' Block 2 x 2 = 16' x 16' x 8' Block 2 x 4 = 16' x 32' x 8' Block 2 x 3 = 16' x 24 x 8' Block 2 x 3 Tall = 16' x 16' x 24' Block 3 x 1, Flat = 24' x 8' x 2' Block 3 x 3, Flat = 24' x 24' x 2' Block 3 x 3, Short = 24' x 24' x 4' Block 3 x 3 = 24' x 24' x 8' Block 3 x 4 = 24' x 32' x 8' Block 4 x 4, Flat = 32' x 32' x 2' Block 4 x 4, Short = 32' x 32' x 4' Block 4 x 4 = 32' x 32' x 8' Block 4 x 4 Tall = 32' x 32' x 24' Block 5 x 1, Flat = 40 x 8' x 2' Block 5 x 5, Flat = 40' x 40' x 2' Block 5 x 5, Short = 40' x 40' x 4' Block 5 x 5 = 40' x 40' x 8' Block 10 x 10 = 80' x 80' x 8' ***note: translation is approximated relatively TIPS: GRID SIZE The grid from Halo Reach is 15 squares x 15 squares, where each square represents a 2x2 block. This translates to 240' x 240' in Halo 5. The grid from Halo 4 and Halo 2 Anniversary however were slightly larger, and are therefore estimated to translate to 256' x 256' JUMP HEIGHT Normal Jump Height = 9' Crouch Jump Height = 10' Stationary Clamber Jump = 12' Moving/Momentum Clamber = 14' Crouch Jump + Clamber = 16' Sprinting + Crouch Jump + Ghandi Hop + Clamber + Auto Stabilize = 21.5' CEILING HEIGHT 16' is the minimum distance a floor can be from the ceiling to to allow your Spartan to comfortably jump without hitting their head. CLAMBER BUFFER Clamber requires space with a with a Height or Width of 4' or more to function. READING MEASUREMENTS Halo 5 Pieces are represented in LENGTH x WIDTH x HEIGHT LENGTH is the value of the side in front of you, or along the X Axis WIDTH is the value of the side going away from you, or along the Y Axis HEIGHT is depth, or how tall the object is, or along the Z Axis

Not to rain on your parade or anything, as you put a lot of work into this, but the direct translation is literally to take feet and convert them into meters, then divide by 3 to get the old forge unit equivalent, as in past iterations, a 1x1 forge unit equaled 3x3 meters. However, as this game has a preference towards multiples of 8, it's best to treat 8 as the base unit of measurement. Unfortunately that ends up with our "2x2" equivalent being a bit smaller than the meter to feet conversion, so it shouldn't be taken too seriously. Play around with different sizes, see what works best for your map. Personally, I like 20' wide walkways.

the pieces wont be direct anyway you slice it, but multiples of 8 work best for finding the general size and it's then up to you to see what feels best. we have a lot more to work with now after all.

How mentally old am I that this constitutes humor: 16' is the minimum distance a floor can be from the ceiling to to allow your Spartan to comfortably jump without hitting their head. I immediate imagine a test room full of leaping Spartans in rooms with low ceilings. Hilarity ensues. On Topic: What the ****'s up with some of these mismatched block and triangle sizes?

Honestly this is a pretty good guide but I'm not sure that it;s 100% accurate. If anyone is remaking a map from an older game that can be seen in forge, you can use a respawn zone to map out a rooms Length, Width, and Height by leaving bottom at .1 and raising top til it hits the ceiling, adding those two values, and then the normal way for width and height. My conclusion is that every .1 in the older Halo games equals 1 in Halo 5.

I was just looking on Reach, the spartan is 2/3 a 1x1 in height but can jump to a ceiling height of 4/3. I am assuming that the spartan is 2 meters tall, the 1x1 is 3 meters tall, and that he can standing-jump to a ceiling of 4 meters. Does this sound right to all of you? I guess what I am not clear about is how did Halo 5 change the standing-jump height from 100% the spartan height to as little as 12.5% the spartan height? I mean, what does that even look like???? And how is it even useful in game play? It is like climbing steps, isn't it?
