Help adding prop to a player model

Hello, ive been working on this player model for a while and what i need to do is figure out how to add this :

onto this model’s head:

I could use some help and any suggestions would be very much appreciated .

You would need to decompile the models, then open the hat .smd and character model .smd, then hack the hat onto the character model, then export the .smd with the hat on the character model, then compile the model.

yes i have both qc files mind telling me what i shoudl replace with wut ? or where i should put it ? but thank you ill keep trying.

You need to edit the .smds in a model making program, then compile.

hmmmm ok well i can do that i guess uhm like i use xs1 6 mod tool, after im done placing the model, know what i should do next, cuz im only familier using weapon models which are alot diff than ragdolls and player models

You will need to rig the hat to the same bone as the head.

hmmmm any advice on how to do that ?
