Interactive Physics based CumSetup Version 1 VAR.
Open the scene file 50s cumScene setup version1
Turn on VR hands and VR hands Collision.
Use the slider to get the CumEffect your after.
Press the auto on button for a looped CumEffect or you can turn auto off and trigger it manually if you prefer.
The man can be put in any position you desire and you can point his thingy in any direction you like for fine tuning the blast trajectory.
This set up is triggered by timed physics so if your computers FPS gets to slow the blast will miss time and not blast far. I Recommend to keep your FPS at 90
The Setting I used
Physics rate 90HZ
Physics update cap 1.
