I have bought for $10 the content in the article described above using the post above. The point is its a project originally for UE 4.13, but its converted much better that UE 4.24.
There is only one error map error. If you convert them to Nanite the trees break!
There is an error in the top left and Lighting needs to be rebuilt and. This content won’t rebuild. It’s so old it will take manual intervention to fix it. That why Nnanite fails below, Ii had not realised that before
Well it looks like the UE5.0 EA importer does its job, but obviously as I have shown the old Content might not be so easy to convert. If you intend to buy something for $10 fine you have not lost much, but if its $70 and the supplier says 4.26 compatible and its not working in UE 5, then you have no grounds to get you money back!
