I've just tried that and the result was not pleasant to see...
It seems that I'm not good at converting faces ... (i follow the video on youtube by trevor poirier on how to convert a face from 2k18 to 2k20 but I don't know if there is an extra part about the facial hair and hair that isn't mentionned, but my face ends up without any hair haha also the nose seemed to be wrong ... and he had no glasses ... anyway

)
If anyone could convert it and post it that would be fantastic ! Or even doing a new face for 2k20 (maybe a more retro one since the one done by Mr Star is Jackson at the end of his coaching carreer)
Otherwise I'll keep using this fictionnal face that we all use haha
