Rigify eye controller does not work.

[higeinu3594]

If you select a bone and it does not move, the controller will work correctly if you re-set either the “Left Eye or Right Eye” weight to 1, but there is one problem. If I save the project and reopen it, the eyes do not move. If I reweight the project in the same way, the eyes move, but it is a pain to reweight them each time.

Please let me know if there is any additional information you would like. I will try to answer as much as possible.

The result is the same whether I use the default character or the original.

Blender 4.2 KKBP 7.0.0 Koikatsu HF Patch v3.30gx

Postscript. I have a problem with the eyes not moving when I close or save Blender. After saving the file, it did not move when I moved my eyes. I can resolve this by reinserting the weight to 1.

I don't know if this will be helpful, but I made a video of the whole process. I really like the creator's add-on and the additional features of Rigify, please let me know how to solve this.

The eye only moved once, not save or restart. The cause is unknown and when I installed KKBP 7.0, when I ran Blender 3.6.9 I got the following error and Blender 2.90 was the only option. I hope this helps.

Hey, I'm sorry but I can't replicate this issue... I can still move the eyes after I save. I also tried closing blender and opening again, but it still worked. Are you using these settings in KKBP 7.0 to import the model, or something different?

[higeinu3594]

Hello. What I found out is that I'm a little mistaken. It doesn't work in pause mode and when I switch back to object mode, it reflects the values that I moved in pause mode. I can move the other bones without any problem, but only the eye controllers are like in the video.

I have tried re-installing the add-on, but with the same result. I don't know if there is a problem with Koikatsu or with the way Blender is installed. The procedure for KKBP 7.0 is

1. impot model
2. Convert for Rigify
3. Check eye movement

Resolved! I had left the add-on “Sakura Auto Simplify” Simplify turned on. It is hard to see in the video, but you can think of it as turning the modifier on and off. I had just recently purchased the add-on and was not aware of its functionality. It was just another add-on that was causing the problem. Sorry for taking your time.
