Converting a Effect model into a Prop model?

Hello I was wondering if it was possible (and if so) how I could convert an effects model into an actual prop?

If it’s spawned as an effect instead of a prop, it has no physics. You’d need to decompile the model if you don’t have the source files, create a collision mesh, and compile it with physical properties. These pages located here and here should help you out with some of the basic information.
