The last few days have been mostly bugfixes and improvements as I am getting ready for this weekend's Beta release. However I did include new animations.
This one is idle2:

She will also now occasionally wash her face. Idle3:

Her BATHTUB_RELAX body state where she has her feet up has also been improved and she will now occasionally hum a song. I'm not actually sure what song she is humming as the Japanese voice actress was improvising. Perhaps the song doesn't exist:

I attached one of the humming songs to this post so you can listen to it. Maybe tell me if you recognize it.
Water sound effects have been recorded so you can listen to her movements produce sounds in the bathtub. I recorded myself moving my hand in a bucket with my microphone.
Additionally I finished smoothing out all transitions for headpatting and included angry mood versions for them. They are the same as the previous post except she is angry so I didn't think it was worth showing.
Lastly, I will try to add distortion to the water surface so it looks like it is distorting the objects inside the water. Luckily I already have a screenspace effect pipeline in my Unity project for this. Expect it after the Beta release. Speaking of, the Beta should come Sunday tomorrow. It should be a relatively big Beta since there is a ton of bathing things for you to try out and provide feedback.
Stay tuned.
