Hey there!
So i’m trying to have a ‘realistic’ paper effect on a block, by putting a paper decal on a transparent block. However, when i set the block transparency to 1, the decal goes semi transparent. It also shifts transparency when i change the view. I’m sure it has something to do with me accidentally pressing something by accident.

Any help would be appreciated. 
You have 2 textures interfering with each other, try moving the paper part 0.01 studs away, it should solve your problem.
Hopefully I solved your problem, if I have make sure to let me know.
I have a texture on the wall behind the paper. Would removing that solve the problem? Usually in this case the paper would just overlap because its on a separate brick which is in front of the wall with the texture. Also the paper brick only has that one paper decal.
Yes, it will.
Another solution I recommend is maybe attempting to use a SurfaceGui with an ImageLabel, it’s far more accurate than 2 parts
Hopefully I solved your problem, if I have make sure to let me know.
