I agree with the posters above. Big thanks to the modder, it's a quickfix to tide us over to patch 7, but I'd also prefer Larian to fix this. My character should not look scared or angry in a repeatable kiss they ask for, especially since we can totally lean into the whole evil power couple thing in dialogue all the way through to the very end of the game.
No other romance gets this treatment for their kisses.
The modding community is doing a great job. And I agree, this issue must be solved by Larian itself for several reasons. Also the facial expressions of Tav have to be precisely coordinated, especially in these intimate D/s kisses, otherwise it looks odd. Unfortunately this mod currently cannot do that. (For example in the kneeling kiss, the big grin when Astarion grabs Tav by the throat doesn't fit. Tav would be more reserved, looking at Astarion expectantly, slightly (!) concerned or shyly, but not laughing like a fool. This is a tense and intimate moment and the laugher doesn't fit. Like that, it looks weird and out of place. Also right before, when Tav is going down on his knees, a more reserved expression would be much better for that intimate D/s moment - - But I really appreciate the mod for those, who use it as a quick fix - especially the happy face after this kiss is an improvement!)
So like the others I still support Larian to take the feedbacks and the survey into account and work on Tav's facial expressions.
