Creating custom nerf model and use it in ue5 using single 3080, Is it workable?

[WilliamLambertCN]

Hi I want to create custom model and import it into UE5, is there ant possible solutions? like the plugin https://github.com/AyoubKhammassi/UnrealMobileNeRF. Even using UE4 is ok. But is it possible to train cutom model in a single 12G 3080? And how long it will take?
