Adding collision to models?

[Stiffy360]

I have a few props and all, but the issue is, they are effect props and have no collision. They have a complicated mesh, so source playerclip is out of the question. Is there any way to implement a collision like this? In a non-tedious process?

P.S. I'm not too sure if this is the right section

The only way would be clip brushes if you don't want to edit the models themselves.

Im fine with editing the models
I just don't know how to do it. >.<

If you deem the collision mesh hard to make with clip brushes, it will be even more tedious and annoying to make a proper collision model, and may be the reason it didn't have one in the first place.

[Fulcrum]

If the model is very complicated source may not be able to handle the collision mesh (the collision model is limited in number of shapes if you choose it to be concave).

If you want to make a collision mesh though decompile the model, open it in milkshape or whatever delete the bits you want people to shoot/walk through. Leaving you with just the "solid" stuff. Also consider having higher harder to reach parts no collided or solid collided to allow greater collision detail lower down where it matters.

Save your model as an smd like you would if you are editing the model. Then in the qc file add replace the current collision model with your new 1 and in the box add $concave. Concave lets you have bits to shoot thru other wise it is "shrink wrapped" so any holes or notches in the side will be filled in by the shrinkwrapped collision model.

Its pretty easy to do but as guy above said to get it right you will need some practice editing models.

You will need to decompile the mdl first using 1 of the decompilers then for the steps I said above open the (usually named) model_ref.smd. Again as guy above said making a collision mesh is pretty much like making a collision mesh from clip brushes in hammer. Also if you want your model to block player but not bullets, decompile 1 of the fence models and have a gander ;)
