Standard build metrics for environments?

I was wondering if there is a list of standard build metrics for stair heights, railing heights, door widths/heights etc.

I understand that each game’s animation can be different. But let’s say for instance, what would they be for your typical FPS with average humans.

If we start submitting environments to the market place, it would be nice if we could standardize these measurements a bit.

Crydev has something that’s very handy (scroll down a bit):

http://docs.cryengine.com/display/SDKDOC3/Measurement+Reference

From the link:
Table Height (top of table) = 75 cm.
Seat height (top of chair, seat) = 46 cm.
Stairs height = power of 75 cm (150 cm, 225 cm, 300 cm, 375 cm, 450 cm ).
Stair steps = 18.75 cm (4 steps will sum up to 75 cm).
Boxes = 60cm x 40cm x 40cm.

Hide Objects (which AI are prone to hide behind) = object that are smaller than 120 cm.
Hide Objects (which AI crouch to hide behind) = object that are bigger than 120 cm.
Hide Objects (which AI stand to hide behind and strafe left/right to leave cover) = object that are bigger than 180 cm.

Jump over Objects (standing, without hand) = 30 - 50 cm high.
Jump over Objects (running jumps) = 50 - 100 cm high.
Jump over Objects (sideways, with using hand) = 120 - 150 cm high.

I did a search, but I couldn’t find anything similar on the UE4 forums.

Hi OPreska,

UE4 has standardized on 1 uu = 1 cm, so those numbers actually seem very reasonable to use directly as they’re based on real-world sizes/heights/etc…

Thanks. :slight_smile:
