Hi ,
i want to know why the most center points from the models are not correct like the Grid of the GTK Radiant . When i put a model on a floor it goes a little bit in the floor . I mean i cant snap them correct to the Grid . Here is a picture of the bottom of the barrel.m3d ( Grid number 1) :

You can see that the center point of the Barrel is a little bit higher than the bottom of the Barrel . Want to know why the model maker or level designer make that ?! At Goldrush the most models go a little bit in the floor too .
sorry when my english is not so good .
(just love those bananas!)
