It worked (so far), I've successfully got skinned Mk14 with props turning running in UE5 (as a simple test).
One question though - does anyone know what units S3D exports the 3D models in? UE5 has base unit 1cm, and if I keep the units the same, you need a magnifying lens to see the model
I tried a multiplier of 100, but it still seems a bit small (Mk14 was 6.25m, I don't think the model looks like that..)
