I need to transfer a model (building) from UE5.4 to UE 4.27. How do I export it correctly so that all textures are preserved? Is there a detailed guide to customize the export. I tried the default way through FBX, for some reason some of the materials are not transferred, some are transferred. How do I model 1:1 from the new version of the engine to the old?
This is a bit of hax, but:
- make empty project
- migrate building/mesh (it will also migrate materials/textures)
- then copy what was migrated from empty project to your old version project
Materials may be incompatible, so double check them.
Also MAKE BACKUP of old version before messing with it.
No. Unfortunately, that’s not gonna work exactly. The old version will simply see nothing but empty folders from the copied migration files.
Do you need to export/import large number of models, or just few (like 10 or so)?
For large number you can try and automate it with python script. Ie. export and save info about textures that are used. Then create import script.
But this requires some learning for python then coding it all. So less work may be just manually doing it all.
A few. A small number.
Do it manually, it is not worth scripting around. Well maybe google a bit there may be script that does what you need.
