I dont know how to make the size of the Decal to the Original Size
Can you not just get the original size from your image properties (if on windows you can right click the image file, press properties and the go to Details) and then set the decal area to whatever the size is?
Okay thanks, i also thought that first but do i need the Scale or Offset?
To be quite honest I am not 100% sure.
offset, if you want to use scale, then get the aspect ratio of your image then add an aspect ratio constraint to the imagelabel
Thanks and i know it now, i forgott that Part dont use Scale and Offset
