Disclaim: This rep is just for ppl who want to find another way to make the model MMD, i no longer use the tool mention in this post to make my model MMD )
Step 1: Check for your model Blendshape for if the model have blendshape for MMD already, because in MMD world, the script there call up for those blendshape to be turned on, if your model have none, then the Script simply cannot meet the Blendshape it need. I advice you check follow this MMD chart: https://www.deviantart.com/xoriu/art/MMD-Facial-Expressions-Chart-341504917
Step 2:
In case your model already have the Blendshapes => Your model Write default on for MMD shape is not on, create a toggle option to turn this on/off when you come to MMD world will help.
Use this tools for the On/Off Switch: Download Link (workupload.com) (The creator of this tools used to be up here but they are no longer here now and i cannot find the og post for this )
In case your model do not have any Blendshapes => You gotta create them.
Using the tools i provide next and the chart up there, copy the name of Blenshapes in the chart and create them from the blendshapes that is already exist in the model. (My boi sadly is from this case, so i gotta create all his MMD shapes by myself)
Tools use for them:

Im sorry for any grammartical or silly mistake i made you catch while scrolling down this rep, for English is not my mother tongue.
This is all my understanding on MMD shapes and stuff up til now, if any of you know another better way, please feel very free to guide us.
