Changes in the legal form of the developer

Hi. We plan to develop the game with a small team using Unreal Engine and for this purpose we want to buy some materials from the Marketplace. Is it possible to use these materials in the game, if you buy them in the name of the founder as an individual, while the game is planned to sell through the game Studio (officially created in Europe)? This founder will be part of this Studio, but this company does not yet officially exist.

That would be ok. But in that case, only the Founder can use those assets on other projects; the team members can only use the asset on that one particular project.
