You'll need to use the 'clip' or 'physics_clip' texture. Whatever you do, do NOT use caulk! Caulk should never be visible to a player unless you really know what you're doing. If you used a lambda, you can load up a preset of it's physics (Assuming you downloaded the same package as me), but it will be stored in JO's map folder.
nono, just create some brushes that closely resemble your model as to not be noticed different when playing ingame, and then texture those with clip or whatever.
