Error importing mesh from blender

i dont know waht can be your problme, but you can try this:

-Try to use FBX instead OBJ.

-Things you can do to check the object:
Export the object to fbx, and try to import again in blender, to see if everything is ok.
You can try to import in another program too, like marmoset, and check if it works.

-if you can export to 3ds, is a good way to clear internal problems on the objetcts, then you can import again the 3ds and export in FBX to unreal.

-another thing you can try, create a new box, then attach the object to the box and export again

hope that help

You have certainly forgotten to select the object in Blender before exporting …

When I try to import from blender I have this error

I tried fbx and obj the same error but if I create a new obj then the import is successful so it seems that somehow I messed with my assets some of them is dublicated and from them I created some variations what can I do?
If I have to create all of them from beginning for sure I will lose my job.
