Futa no collision with vagina

[Tesladriver09]

Hello guys, I have a problem with vagina collisions on my futa setup.

I'm using the following mods:

 

• CBPC
• CBBE 3BA (Full CBPC selected)
• The New Gentleman
• TRX Futanari SOS addon
• TRX SOS Addon for Males
• OStim standalone
• Obody

 

Problem is that in a futa-female-scene there is no collision between penis and vagina.

In a scene between male and futa or male and female, there is collision. That's strange.

I think if there is collision between male and futa, the mods are correctly installed.

Has anyone ever had a similar problem ?

thank you
