Licenses and Licens terms

Hi everyone,
Question is: while I was making VFX for movies i could buy assets, textures and models and use them how i wanted to create whatever effect i needed in that movie and my client would have rights to that movie. I am wondering how its working with VFX for games. Final product will be game so its not reselling textures or materials. I am making some VFX as freelancer and I buy some asset from lets say fab like textures,models or decals, can i give my effect that use them to some company to use it in their game or this company would need to buy rights to use them?

No, you can’t, it’s illegal, the same with movies. It’s easer with movies because you don’t give the resourses for your client. You give them the final product. The same with games. Game is a final product. Resourses aren’t. You can’t give to the client the effects you made with side resourses. You need to create new unique resourses for each client.

Thanks! That what i thought so.
