Thanks for detailing those figures - it’s super useful. and I also just read your other thread - [UE5.0.2 Landscape Mode Broken? - #4 by DemenzunMedia](https://forums.unrealengine.com/t/ue5-0-2-landscape-mode-broken/577790/4) My previous project used 5x5 tiles of 4033 res 20165 - is that good to convert as is? or should I expect some cropping or padding on those figures? And I was just starting a new project with 3x3 tiles of 8129 res of 24387, should I be trying to use 24481 now? but I’ve fallen for the one that’s a prime number, am I now stuffed due to limited divisibility? I’m trying to avoid cropping/padding if at all possible. What you mentioned about the memory makes sense. I’m technically not using world composition in UE4, but I am importing terrain tiles in using a plugin called TerraForm Pro, Do you think there a possible workaround of still going via UE4 and then converting into UE5 to avoid the RAM limitations? as I don’t think I’m going to be able to upgrade my memory any time soon, but I would really benefit from working on a 24km terrain for this project. Out of interest do you use the command line option for WP converter or GUI option? Do you think the FPS I mentioned in my earlier post is to be expected, or is there some scope for improvement using appropriate new tile multiplier dimensions, or perhaps other config tweaks? --- _[View the full topic](https://forums.unrealengine.com/t/ue5-world-partition-massive-map-sizes/510107)._
