Shape Keys+

I tried to recreate the issue to get a better idea of what you’re referring to. Is it that, when you change the blink/smile shapes’ relative key from Basis to a new key (say, Basis2 ), that the blink/smile shape keys are still basing their deformation off of the original Basis shape key? (Meaning, when you set the values of the blink/smile shape keys to 1.000, the shape reverts back to the way it looks in Basis without the wrinkles of Basis2 .)

Yes, you are right.

@MontagueMGM

In that case, you can fix it by selecting all vertices in the blink/smile shape keys and using the Blend From Shape operator under the W (Specials) menu in Edit Mode, then pressing T or F6 to open the properties, and setting the blending key to Basis2 , Blend value to 1.000 and enabling the Add checkbox. Note that if you don’t move Basis2 to the very top of the shape key list, you still have to set it to 1.000 to have it show up in the blink/smile shape keys.

Thanks a lot for your advice. I try it & it work for 1 shape key at once only. If I set the slider to value: 1 for only 1 shape key, then it behaves normal. However, if I set the slider to value: 1 for 2 shape keys (e.g. smile left & smile right), the wrinkle is doubled, which is not what I wanted .

I play around with it & found out a way that work well with what I wanted . That is if I move the new basis shape key to the top (above original basis shape key), all other shape key deform from the new basis shape key. But the original basis shape key must not be deleted & no “blend from shape” is required as well. I don’t know if this is only applicable for me, but it might help other people with the same problem. Thanks again for the advice, appreciate it @MontagueMGM
