Metallic paint turns into a white bonnet ? [solved]

[krisduv]

I was making some tests and this is the second time it happens, it's weird.
The first time was a random colour in metallic.
This time, it's a special colour metallic paint.
In GT Auto, it looks perfectly normal.

And as soon as I get out of GT Auto, the bonnet is white.

What happens if you remove all decals from the bonnet?

 

[krisduv]

Nothing changes. I even tried to delete every decal. So basically just a painted car.
Still a white bonnet.

EDIT: well I tried to keep the bonnet metallic and the rest of the car all white because why not. And it works.
Doesn't solve my problem at all though

Haha my last test wasn't that stupid after all.
I painted all the car in white and then every part one by one with the special colour, starting with the bonnet.
And it worked

PD logic

The white bonnet actually doesn't look too bad, I can't lie.

I don't know why, but the bonnet with a different colour, that's usually a big no for me
