Quote from blackdogI agree that's confusing, I would expect some float numbers... but still the object in Blender is completely wrong! The cube in Hammer is as big as a the shoulder of the player model, what looks like a volume of about 20 or 30 cm^3, a 10m cube in Blender should encompass the same model at least 5 times. It's basically 1:50 scale ratio by the looks of it.
What happens when you export from Blender to Hammer? Is the size scaled appropriately to the player?
Wonder if conversion tools you use are rescaling the objects.
Blender to Hammer keeps the same scale. For example, the player height is 73 Hammer units tall so a matching model would be 73 meters.
