Unreal crash when loading asset.

Hi Guys,

I just start learning lighting with Houdini Solaris and UE.
Iḿ facing some issues with UE, when i’m loading a environnement in solaris, it worked and i can render it.
But the same environnement keep crashing in UE, because i don’t have enough video memory.

I have a Geforce RTX 1080Ti with 11Go of ram.

Sorry, maybe i don’t have the right words, i’m new.
What can i do?
Please.
Thanks.

D.

My question, is how to handle big assets?
