Fixed Trailers

Hello, after a long absence, I'm back again.

This archive fixes and adds features for standard trailers.
And so, what does he fix/add:

Artict1 :
- Fixed normals
- Added glitter
- Added doors

Artict3 :
- Fixed normals
- Added doors
- Fixed headlights

I didn’t think of what to put inside these trailers, maybe someone will figure out what to put in them, the models are not blocked, you can experiment.

P.S. If you like these files from me, maybe I'll post something else.
And also, offer your ideas in the comments, or send me a PM in VK, what else can be corrected or added.
