If you go into the properties of a part you may be able to see a box called transparency. Transparency property goes from 0 to 1 so if you want a tint that you can slightly see through go for like 0.7. Otherwise if you really want to script it

TintedPart = game.Workspace.part.Transparency

TintedPart = 0.7

--or

function PartILke()
TintedPart = 0.7
end

There are many ways to go about on this to make it awesome. And if you want a frame you can put in a decal wit ha transparent block. Please refer back to me if more questions abotu this.

No, it's just the Transparency property, just change it to something like 0.5 or something. If you WANT to use a script then change the Transparency property like how you would set the Anchored.

Final Product

local part = workspace.Part
part.Transparency = 0.5 --Half transparent

Hope it helps!

script.Parent.Transparency = 0.5

Place this in a Part. Also, you can just change the Part's Transparency manually.

No it does not require any scripting knowledge its quiet simple really all you need to do is go into the Bricks Properties and look for transperency and change it how you want.
