There are a few things going on there. In Please Me, it's that the range of movement set by the State Machine for that State is bringing her head too far up by using a positive value that takes her too far away ?. We like her and want her closer. I have another version in the works that solves that, plus adds another angle that tips her head up so you can watch her pretty face gobble your knob.
In Blow Me mode, I'm pretty sure that has to do with the head angle pos limit being set too high. I found an error in the Voice Controler command for Tip; it's missing the parameter to set the Head Angle X Pos Max, so I would advise either adding a command and setting it to something in the range of -3 to 2.5. I think now it's keeping the value from whatever previous mode was set. I have tweaked that value a few times to get the moves just right. You can also just use the manual sliders in the scene to play with that. Also in Blow Me mode, try telling her "deeper" so she's not going "off dong", a most undignified state to be sure.
I will post an update soon, but one caveat is that Auto Thruster just got a MAJOR feature added that let's me control the origin point of the moves by parenting it to an empty atom and then moving that around, so what I have in the works right now will be followed soon after with an even more awesome update. Stay strong, we'll get through this crisis.
Anyone else having issues with the head angle bugging out in "please me" mode? The same thing happens if I go from tip to deep throat in "suck me" mode.
