Plugins [Experimental] Alternative Futa

Big thanks to everyone that's been flagging bugs and to everyone else for bearing with me. Update 22 had a lot of changes under the hood that made rare issues happen more reliably. I'll keep working through them as we find them.

• Improvements to collider sync after loading
• Better tesselation on initial load
  • This reduces (but does not eliminate) the small gap between the pelvis and male gens
  • You'll still need to load one of HuntingSuccubus' tesselation or subsurface scattering plugins to fix it
• Improvements to race conditions between reloading and skin vertex updates
• Fixed issue where successive reloads may alter the skin
• Stability fixes for repeated reloading of skin and plugin

• Fixed issue with skin not reloading in some scenarios.

• Refactored a lot of the initialization code.
  • A lot more of it is done synchronously and should hopefully result in fewer race conditions.
  • Might also break things. Let me know!
• No longer adds male genital morphs to the female morph UI.
  • Should also no longer throw "Could not find morph" errors when loading a scene.
• Now auto-enables 'use male morphs on female'
  • It will also zero out all male morphs if the setting wasn't previously set. Otherwise the 'default' male morphs would mess up the model during general use.
• Added a new morph "AltFuta Pelvis Smooth v1" that blends the gens a little better.
  • It's just a combination of built-in morphs, so it's far from perfect.
  • Works best with a Z offset of -0.0085 or so
  • 
• Other small tweaks that I can't remember.

• Fixed bug in latest update that cause penis physics to break

• Fixed bug where testicle controls weren't enabled

• Added some fixes for AltFutas in SubScenes.
  • Thanks to @WeebUVR for flagging! Should hopefully now work in his insane scenes.

• Brought back the option to hide the male pelvis.
  • Note: this turns off any pinning or other geometry changes.
• Merged the material options for the pelvis and penis into one.
  • If anyone has a good reason to keep them separate let me know. Otherwise it just seems redundant.

• Fixed issue where FPS drops after loading the plugin and before character UI is loaded.

• Geometry
  • Changed the pinning on the front of the pelvis to remove jagged lines
  • Changed the pinning on the perineum to be further forward
    • 
      
    • Still works pretty well with Weeb's textures but might require adjustment
    • 
  • Added a "Vagina Hide" morph based off of Particle Pinnacle's vagina forward morphand some built-ins
    • This fixes some odd shadows with the new geometry
  • Fixed collision between testicles and the colliders in the pelvis and vagina
• Material Options
  • Will now load all the saved body textures by default. Added 'merge load' setting to allow for the previous behavior
  • Fixed issue with some settings going to 0 when
  • Various fixes and improvements. Should hopefully be well-behaved now.
    • If you see issues, please let me know.

This update is a long-time coming, and it took a lot of investigation, custom tooling, and trial & error to get here. The end result, though, is what I'm hoping will be the final version of the geometry so texture work can start.

Huge thanks to @WeebUVR for helping me work through all this and creating some of the first compatible textures.

General Changes

• The only major setting is now whether to show/hide the vagina.
  • The male pelvis is always drawn and don't use the base textures anymore.
  • Consequently, there's no longer a material UI for the female pelvis.
• Added Save/Load of presets

Geometry

• Vagina Hidden - Now Default
  • The perineum now stretches around the vagina up towards the anus.
    • The vertices are 'pinned' in place and should adjust
    • The stretching can cause some odd shadows. I recommend using ParticlePinnacle's 'GM vag only forward' morph to improve it. I may add a version of this in a later release.

  • Non-visible parts of the vagina mesh are now hidden.
  • If you see small gaps between the pelvis and body, it's likely a problem with tessellation.
    • HuntingSuccubus' body smoother should fix it
      • https://hub.virtamate.com/resources/automaticbodysmoother-session-plugin.5235/
  • WeebUVR has already done some texturing work to smooth this out, and it's looking pretty good! I will let him release that when he's done.
  • 
• Vagina Shown
  • I've cleaned up the geometry/pinning and hid most of the perineum.
    • Unfortunately, there's no way to properly pin the back of the testicles to the area around the clit. The geometry is too different. This still needs to be 'folded' in.
    • The unused portions of the vagina mesh are now also hidden here as well.
  • Unfortunately, these will need likely need a separate set of textures from the 'hidden' version as it might be difficult to get a texture that works for both.
