sps is free to use and easy to set up, im sad people still sell setups for it.
to test if sps is working, and you have wholesome config installed in your vcc. go to tools, wholesome, click on your avatar and click add test penetrator. if you have your own toy youd like to use, make sure it has a plug on it by either creating a game object and adding the SPS Haptic Plug, dragging the object onto your toy's beginning armature bone.
if you need visual help you can dm me your discord and i'll walk you thru it.
