Shader graph adds background to my texture
I am making a dissolve effect that works on images, the dissolve works fine but shader graph adds a gray background to my texture, even though it is a png. Any idea why?
Thankyou, the picture provided shows my problem.
I have a similar issue that unwanted backgrounds are added to Main Preview although sprite itself has no background. I imported sprites from Unity Asset store and try to play with it to learn shader graph but I cant find a way to remove auto added background. ( i attached the image to show the problem)
Unity 2020.3.26f
If anyone has a clue to solve it, that'd be very appreciated.
well, I somehow solved it by connectin alpha from sample texture 2d node to alpha in fragment.

you need to multiply the alpha with the alpha from the blend node in the bottom right, to have the effect be transparent.
so a split node, and use the A output to multiply with the blue line that goes into alpha of the master output
