ISSUE A wheel desapeares when exported to kseditor

[Diego Da Rocha]

Hi there, first time posting so be gentle, i'm trying to make a burnout car, it's my second car so im trying my best but i always find issues, bugs or anything a could do wrong. I was making a DIY blur fo the car and tried for first time on asseto, but after that, the next export from 3dsmax did a wheel to desapear from the car, it is there the meshes, also active, render, and not transparent. The funny thing is, the blur actually works, but i dont have a wheel or tyre or disc behind, and if i export it to Kseditor v6 it shows me every wheel, but them when exported to kn5 CM shows me the truth, there is no wheel. Can someone help me? Srry for the english guys.

Here was the first time it worked

Here is how it looks on 3dsmax

And here what really happens :/
