i just want to know if i have a 3d model of a person can i use the ghosts gbx importer and import cyborg.biped than but its nodes or skeleton or whatever onto my model? like i do not mind if it is a inferior method or something honestly i just want to be able to get bipeds ingame.

That's the way most people do it with custom bipeds. Importing the cyborg bone set will make it so you can use the cyborg animations, collision, ect. Basically, import the cyborg.gbxmodel, line up the bones with your biped, then rig it to them. Export, compile, fix node list checksum. Bang, there you go.

Yeah it should work fine. But the rig will look like complete garbage. (coming from someone who rigged a bioed once 5 years ago)
The method that is in tutorials and told to be used is where the bones come to a joint, and they need to have those joints have a percentage belong to both bones at once, otherwise ingame when thosebones are bent, like say arms at the elbow, it will look like a folded piece of paper at the joint.
