Rules of Common MMD Models…
…and How to NOT Break Them

TDA, Sour, YYB, Cham, and Montecore are some of the most popular model types people like to use for models, but some of their rules can be confusing and are often broken (whether intentional or not). So here is a basic rundown of all of these model types’ rules, referencing directly from their original README.

TDA:

Know the rules established for using the TDA models. Rules for Common MMD models.

  • The vocaloid models must be used in a way that follows the Piapro Character License
  • TDA is not responsible for any damages that’s been caused by the models
  • If you want to use models with TDA parts for commercial use (making any kind of money off of it), you need to get permission from both Crypton Future Media Inc. and TDA
  • Editing is allowed, but there are some limits:
    • You don’t need permission to edit
    • The model must be recognizable as TDA (no extreme edits)
    • Remove the CRYPTON logo on the ankle if it’s present, simply replace the body texture with body00_MikuAp.tga
    • If you distribute your edit, you must include both the Japanese and English TDA ReadMe along with it, call your edit TDA Styled ______, and credit TDA along with the editors.
  • You cannot redistribute the original model without editing
  • You cannot edit the model into a base
    • This includes both swimsuit bases and naked bases
  • You cannot use a TDA part on a non-TDA model
    • This rule is okay to break IF you’re editing the model for a picture or video where TDA Append Miku is the main focus, but the edited model CANNOT be redistributed

Model creators…

… put in a lot of time and effort into their models, and they give it out to the MMD community for free. We need to start paying more attention to these modeler’s rules and respect them. More and more modelers are taking down their models and hiding them behind layers of passwords because of those that disrespect their terms. We are able to download these models for free, don’t take it for granted. Make it a point to READ those ReadMe.txt files included in your model’s folder so that you know the creator’s permissions… translate the ReadMe.txt file if you need to.
