New huge content update! Yay!

• A new type of behavior: "Pony on Top." That's what you think it is! At present there's one activity you can do which is to be a female avatar and interact with a male or herm friend. More on the way and all of this will port to Besti X, too, so it's not wasted production. New content is always nice <3 You can use the Besti Toy on dildos now <3
• Significant AI improvements regarding look targeting and some improved animations
• New post-processing shaders. One just makes the graphics look better, and another gives a "toon" style appearance. If you have a potato computer you can also turn it off completely, which will make it run better than it ever has.
• New fluid shaders. Now they're nice! Still the same underlying non-compute SPH algorithm  system which isn't spectacular, but the new shader makes it look a hell of a lot nicer.

Besti 9.85 changelog

• The 3D pony arousal gauge is in a bad spot. I'll move it in the next build. Thank you for reporting the issue! The AI controls this and I just failed to tell the AI how to do it. The fix should only takes a few hours to implement so I'll get that in the next build.
• Urine from males is full of poor-looking bubbles, but urine from females looks as intended. I need to dig into this and figure out what's going on.
• Alwaysfree forest has unexpectedly intense lighting. I'm not sure why. I probably need to recompile the lights.

• There is now a Pony On Top behavior that allows you to be fucked by a pony. Besti Toy on a dildo works well for this. You can thank Vaalyn for sending me the tools I needed to test this properly (hue hue hue.) It only works with a female avatar and a male or herm friend, but I'll work on additional pairings in this position on the Besti X port.
• Friends have a new eye option called HeartSparkles. This is essentially the Deer eye, but it has a little cluster of hearts in the corner. It's pretty cute.
• New post-processing options have been ported from Besti X. This changes the visual appearance of the program if you want to try them.
• Some animations have been changed to look nicer.
• Several internal algorithms have been ported from Besti X that improve the overall look and feel of the AI.

• Added a new internal category for the friend AI to process. This is a spawn point type where you are laying on the edge of the surface and the friend is on the ground next to you. It is effectively the inverse of Standing.
• That will be referred to Pony On Top or P.O.T.
• Updated the wording in the menus to remove references to Patreon. Still one more but it's so integrated I'll have to fix it another day.
• Added an option to invert the controls in the P.O.T. position.
• Wired that option into the settings system.
• Modified the save file to retain your preference on if you want to invert the P.O.T. behavior with the Besti toy.
• Put in a failure contingency that updates your save file if you load a previous version of the save file that doesn't have that option. 
• Created the conceptual pathing of the new position. Friend hops off the surface to get in front of you. From there there can be behavior options, and there's another branch called Mount Me that has other options. Mount me will have inside of it penetrative options that the friend can use on you, whereas on the base branch the friend can do oral on you or a variety of other things. This will give us options to work with without the menus becoming too complicated. 
• Animated this behavior. The new behavior is POT Vaginal, and consists of 78 animations as seed data for the animation parser. If you're new to Besti, Besti uses a system to generate variants of animations based on skeletal animation that I make in Blender. The actual animations are never used in Besti, but it generates close approximations so a looping behavior is never quite identical.
• Configured male friends to get an erection when you ask them to mount you.
• Fixed an issue that happens in House Party where a background process crashes if you don't have any video files in your video index.
• Fixed the grabbable that was making a thumping sound on entering House Party. The key bowl was juuuust high enough to trigger the impact effect once physics activates. 
• Increased the accuracy of body look targeting.
• Improved look targeting in general by backporting the new orbital targeting routine I wrote for Besti X.
• Added a penetration sensor to your vaginal/anal region so I know how penetrated you are/how quickly you've been penetrated.
• Wrote appropriate code for that.
• Made significant scripting improvements to improve performance. 1 to 2% difference, but it does solve a lot of potential weird issues.
• Fixed a logical issue with the arousal AI subroutine. On male and herm friends, the friend's state of erectness is based on how aroused the AI is. The problem was that at precisely 300 arousal, the penis erection subroutine didn't know what to do. At this precise amount, the penis was updated with a status that was neither flaccid nor erect, nor was it in between. What was happening instead was that the physics system was competing with the animation system, and when the penis is asked to interact with a collider (such as when it's penetrating you) the penis vibrated itself free of you and popped out of your abdomen like an alien. Obviously that's not the desired behavior so I fixed that to have 300 arousal be a valid arousal level. 
• Fixed an issue that caused semen to gurgle out from your chest when your friend ejaculates inside you. Again, humorous, but unintended. 
• Improved the rotation behavior of standing friends. 
• Revamped the fluid system. This has a bit of a performance impact, but I feel like I've offset that for slower computers to be able to deal with in other areas.
• Made stallions cum significantly more cum.
• Increased volume of mare secretions when aroused.
• Made urine look nicer
• Added new post processing options that I backported from Besti X.
• Added internal code for HDR support if you are using an HDR display. This was written for Oculus Quest support on Besti X, but it was easy enough to port over to Besti 9.
• Made the artwork for a new eye type. Heartsparkles. Thought it was cute.
