All started 2 years ago or 3, That I was doing a map and I looked at the 3ds to rsm browedit plugin. At first, I thought that it was going to be as easy as having a .3ds file and convert it, but, it was much more than that. I had a lot of crashes, bad positions, horrible textures, a headache really but that was the beginning of a very long way. In those years, the information and references about this area in Ragnarok was almost null. Hence everything has been matter of trying with tests and errors even to this day.
Regarding your inquirie if all of this is self taught, I would say, that yes it is. However, everything has been possible thanks by the fact that I had the chance to work in cooperation with great people that you can see in some of the credits in the topic or videos.
Everything has been self taught until weeks ago that I begun to study a mastery in animation and 3D modeling. Its a long journey, we'll see how everything goes.
Edit: also to everyone that is thankfull for this, please, don't forget that we must be thankfull for that people that developed the tools to make this real.
