How do I fix this bug? (GTA V)

[FloatStreak]

Hello, folks.

I recently worked on a custom MLO with custom models and interior and so on.
Now I was importing my custom models into 3DS max and exported them with the original file. In the end it looked like this:

I brought own textures with it, but CodeWalker doesn't seem to load it.

And if I load into the game, this strange bug occurs.

Does anyone know how to fix this?

Thanks in advance.
