A lot of “releases” lately are vehicle packs (which can be made in 10 minutes if you’ve downloaded ported models). Well, okey, sure.
But a lot of them, judging by screenshots, have problems with lighting.
I won’t be surprised if they have problems with collision, with handling, they could conflict with vanilla vehicles and it’s an often bug where vehicles duplicate when damaged.
So, please, don’t just dump these packs like crazy. Test them, check for problems. Thank you.
