When applying Instance.new(“Decal”)'s onto an instance, the texture will NOT appear until the item changes, like if it changed colour or if the instance is cloned.
Video:
Note that, when other people place decals, it will appear, as this is client side:
Some additional information:
This will not occur on studio and will only occur client side.
Example games that are affected by this bug
To debug in these games:
Create a world [Go to My Worlds → Create new world]
Place down a sign on the grass, using !sign [text]. If successful, the texture will not appear
Expected behavior
What is expected
The Decal will appear on the client side and server side to all people.
I marked this as somewhat urgent because a lot of games use Decals like this to apply textures.
