OpenUp!
Preamble
In short, this plugin allows girthy and long penises to penetrate both vagina and anus easily, no more fighting the pussy, only fucking. I am fairly pleased where the plugin is at right now, although there's still a lot that can be done. I'd like to thank all the morph creators whose morphs I've used to make this plugin happen.
Usage
It's pretty straight forward, add the 'AddToFemale.cslist' to the female atom, and the other one to the male, but it's not required. I've setup some pretty good defaults, so you should be good to go.
I recommend adding AcidBubbles ColliderEditor to both male and female. Check that the Gen1 and Gen2 penis colliders fit nicely slightly inside of the penis.
Your specific penis/vagina might require some additional configuration. There's a lot of options, hopefully you only need to play with the Global Multipliers, disable 'Auto Girth' to change them. If you want to configure even deeper, you can find 'Vaginal Config' and 'Anal Config' at the bottom.
The male one contains some additional penis colliders, but they're a bit finicky to configure and any change to the penis morph will require re-configuring. I've included some plugin defaults that you can find if you click 'Plugin Presets' > enable merge load > select existing > search for OpenUp.
Known issues
I did notice that I get different results with different physics settings. I use Physics Rate 60hz and Physics Update Cap 1.
- Imperfect collider group toggles
- Some penetration angles have a hard time detecting if in anus/vagina
- Long penises can escape out of belly/back
- A need to refresh 'Ignore Colliders' when adding new penis colliders to male
- Need custom female colliders that only deal with containing penis
- Does not support double penetration
- Existing genital morphs and pose morphs might look weird when using this plugin
- Collider rotation for Male gets a little wonky if penis bends too much
- Attempt to support AltFuta
- Load and save presets
- Improving the anus/vagina penetration detection system
- Auto expansion of face morphs during oral
- Custom morphs to enable greater accuracy and fewer configuration options
