Conversion of Game Units

• 1 DromEd unit is roughly 1 foot.
• 1 DromEd unit is roughly 12 UnrealEd units.
• 1 Doom Unit is approximately an inch.

Demigod found that 90 doom units = 8 dromed units. It may feel slightly to small height wise but in third person looks spot on.

The average dromed door being 8 by 4 units or 90/45 doom3 units. All the conversion I've done on this map so far uses 90/8*dromedsize = doom3 size.

Note by Ishtvan:

• 1 Doom unit is supposed to be exactly 1 inch (I've seen in the code where it says "Doom to meters: 0.0254")
• 1 DromEd unit is I guess approximately 1 foot, so it should be approximately 12 Doom units to 1 DromEd unit.

Note by Springheel:

• Despite what it says in the code, the agreed upon standard is that 1 Doom unit basically equals 1.1 inches. This looks best in game.

Tips

Since the units are about 11 units to the foot, a quick and dirty guesstimate is times 10 and 'add a bit' up to the next grid . So a room roughly 24 by 16 by 12 foot high = 240 x 160 x 120 so call it 256 x 192 x 128 units. Put in a human AI to get a sense of scale when evaluating sizes.

Blender

To match Blender's grid with the Radiant grid, go to "View"->"View Properties"->"Grid:Spacing" and set it to 10. This matches the DarkRadiant grid set to "1". Usually it's better to just turn on the edge length rendering: (Buttons view: Mesh Tools 1 > Edge Length) to see how large the objects really are.
