What are you attempting to achieve?
Putting a transparent part with a decal on it on top of another part
What is the issue?
The decal in question appears transparent, despite the uploaded image not being transparent nor the transparency being set to anything other than 0
What solutions have you tried so far?
Uploading decal through the website rather than studio, removing part and making a new one
so u are going to put a transparent image as a decal on a part and you still can see that part color?
if so open the properties tab and set the transparency to 1
