The problems are still unsolved and the packs are still available to buy on the marketplace.
Epic: stop them from being purchaseable until the problems are fixed, as people can’t use them as they are supposed to and expect when buying from the marketplace.
As there is no material assigning via material slots buyers can’t change colors of the models without exporting them and re-UV them which often breaks the geometry.
Because of this wrong workflow, they even have the same model a few times in the packs! E.g. same car in blue and red, instead of just one car with proper material assigning so buyers can exchange the color/material by themself!
