For the past few days I've been trying to make a new weapon based off the plasma gun. I think I am losing the attachment points on the receiver when I remove the mesh from the plasmareceiver.nif and add my own mesh. I've been checking forums and the youtubes but haven't had much luck. Here are my steps: Create my new mesh OBJ. Use bodyslide to convert it to a nif. Copy plasmareceiver.nif. Add my BSSubIndexTriShape to the copy and add a copy of the old material info over. Delete the old BSTriShapes *Note the connection points are still in the nif In creation kit: Create copies of the mod_, miscmod_, co_mod_ and the weapon itself. Modify the standard receiver OMOD to use my new nif. *Note the mesh displays in the preview window. I open the copied weapon and open the templates. I clear out everything in the default template and add in my new receiver. If I close the window and reopen I can see the new receiver mesh in the preview. However, if I add in other mods the mesh disappears. So, now to the attach points idea. If go back to the mod for the receiver and remove the attach points and click "Collect From 3D" the attach points don't return. But if try the same with an unmodified receiver the attach points return. If anyone has ideas or another method for starting a new weapon I'd appreciate the help. Thx in advance.
