How to get true zero gravity

If there is a less complex way to achieve this then sorry but I just remembered a glitch to make sv_gravity affect props and ragdolls as well. If you download http://www.garrysmod.org/downloads/?a=view&id=64791 and activate the anti gravity chamber then set and sv_gravity value while in that chamber, next time you load a map the sv_gravity value you set will affect everything (including crossbow bolts, which is highly confusing if you set a negative value)

I take no credit for that map

dosen’t sv_gravity affect props?

Only if the map is loaded with the lower gravity

if you did that, then the only way you could get around would be through no-clip

sv_gravity 0
reload

I think that this will make the Gravity setting affect all props…
