Collision sphere in models

Just a general question - is there an advantage to creating a collision sphere in a modeling program as opposed to code?

Any performance gain (faster creation of the sphere?)

I have done it with code thus far but do have the option of just using mdoels with the Csphere already put in there.

Would the code to use it be very different?

In a modeling program, it’s usually easier to create a sphere that exactly matches your existing models. Other than that, there’s no particular advantage to either approach.


Thanks for the quick reply!
