Add the latest galleries, including those of the new terrains in Rocket Racing for UEFN & Creative

I would like to see the new Creative & UEFN galleries, including the new terrain galleries, added to the Rocket Racing Editor for UEFN to allow for even more impressive and immersive worlds for players

I also hope that the new features (galleries, etc.) for Rocket Racing will be maintained, as it is still present

Thank you!
