[HELP] Costly Collison Error (NOOB)

Hey everyone, so I’m trying to rig a model right now to GMOD, but whenever I compile I am getting the error



WARNING: COSTLY COLLISION MODEL!!!! (45 parts - 40 allowed)
WARNING: Error with convex elements of C:\Users\Demersuss\Desktop\model/physmodel.smd, building single convex!!!!
WARNING: COSTLY COLLISION MODEL!!!! (105 parts - 40 allowed)
WARNING: Error with convex elements of C:\Users\Demersuss\Desktop\model/physmodel.smd, building single convex!!!!
WARNING: COSTLY COLLISION MODEL!!!! (105 parts - 40 allowed)

Now I am very new to modelling. What does this mean? How do I fix it? Can someone break it down? What are collision parts, just parts of the model? Any help would be helpful.

add $maxconvexpieces 128 underneath the $collisionmodel

Unless it’s a ragdoll, in which 32 is a hardcoded limit.
