Hello. I am modder who cannot do modding because of mandatory military workout for this time. So I thought my skill will be useless in this area, but not worthy to betray on that time. So, I will make some lecture and reference of Jbeam and Json format. It is written to make a reference about Jbeam and its usage with some Example. Another reasons of why I am doing is my vision. I was able to think what car design I would challange for. And it can be some help who is thinking about automotive design and make their concepts to semi-real. https://docs.google.com/document/d/14-fxr64NmFOLxf7QNZN9cyqjoPdkBeAyDFHOJcKarKw/edit?usp=sharing Actually this is almost Finished in Korean but, I need to translate this into some languages to make it available in documentation. in fact I dont know how to make documents in this site. So i need some help to interpret this into some languages. Would you help?
