I have played in the past with the character customizer from Black Desert Online, which was one of the most complex I have seen done in a game, but this week I got the opportunity to play the Bless Online game and oh man, that character customizer is a beast. Anyone willing to check this there are currently plenty of streamer videos at Youtube showing then expending a huge amount of time just to create their toons, not because it was complex, but each attempt bring so many cool stuff to see that it was impossible to not try each combination. Each race has special things to customize, since two of them are animal like creatures. I did have fun with it and the characters made are truly what I wanted to create.
PS: The experience teaches a lot on how it can be done and I do hope to extend this tool from mlindborg to have something stunning in my game design.
