Tinted windows

Hello!
I'm curious about how to tint windows in slrr ?

not possible to do it ingame yourself, you can use it on car if author added them to the mod

Okay, thats what I thought. Thanks for the quick answer, any pro-tips on how to do it in photoshop ?

No chop matte. Can be made in 3ds only so u can change the matterial settings of the part and export to SL
