-This goes in the
retro-porting forum.
-There are many threads in this forum about models that appear as cubes.
-99% of the time, a cube means that the game can't find the model (aka the path is wrong in the dbcs or the folders you made have wrong names, etc).
-Have you tried swapping the model with another one instead of editing the dbcs to check if the model really works?
-You are giving almost not information or screenshots of your model, or your dbcs, or the converter you used.
