I’m not very familiar with UE, but NP5 put up a wiki post about importing from Blender to UE (it’s just a video link). Did you check that one yet?
As for which approach to take, my (very much non-expert) opinion is that there are two major things to take into consideration:
- How sophisticated is the graphics style of your game? Is this going to make use of all the new UE5 features like Lumen and whatnot, or is it going to look more like, say, Viscera Cleanup Detail? Both perfectly valid, but imply very different requirements.
- How closely is the player ever going to look at this particular asset? If they’ll be driving the truck, that’s going to demand more detail than if it’s just a random object kinematically shuffled and teleported along a highway outside the playable area.
I mean, there’s really nothing inherently wrong with using an atlas either - it all just comes down to what best fits your use-case. Good luck; these look very solid so far =)
