You might be able to get away with fobbing it down a little and say like heights 1-3 use one animation, 4-6 use a second one. With 10 different 'notches' on the slider, you'd need 100 animations for each different height to match properly. And vice-versa the height 2 sim tilts their head down to meet the height 1 sim.
If Sim1 is at height 1 and Sim2 is at height 2, the animation would need to be adjusted so a height 1 sim can properly tilt their head back to properly align with a height 2 sim. Would two sims at height '1' use the same animation as two sims at height '2'?) Let's say Sim1 and Sim2 are both at height '1' (of 2) The animation would not need one sim to 'bend' over to align the kiss properly. How many notches are there total? 5? 10? Let's say there are only TWO. Imagine there is a 'height' slider in CAS.
