Trying to export a Gmod workshop car model for SFM, but i have a problem.

[AGS]

So i got this Scar pack from the GMod workshop.

And i plan to export it to use it in Source Filmmaker.

Now, one of the things i look for in a model is if it casts dynamic shadows or not.
If it doesn't cast shadows, it will look odd under light in SFM, and i won't use it.

When i spawned the Scar it did cast a shadow, but when i went to the spawnlist and spawned the actual model itself, it only casted the ugly default shadow.

[I]The car on the left is the car spawned as an Scar, you can see the shadow casted on the wall.
The one on the right is the model itself spawned. It's only casting the default shadow on the floor.[/I]

Weird, it should be using the same model, why is the model not casting a shadow?

I want to use this model, but only if i can get it to cast the dynamic shadows.
