Hello,
I started with blender recently and I’m trying to take a 2D image and save it as a 3D image.
The rendered image has a transparent background, and the shapes are partly translucent which is fine. However i get an odd grey blur appearing around the edge of the shapes which isn’t in the 2D image (pics below). Is there a fix for this?
Thanks!
Thanks for providing your node setup 
Would you also share the “additionalityv2.png” file?
Ok cool. Here’s what’s happening- you’re using the Alpha output of the image texture, but the image doesn’t actually have any alpha information. Here’s what happens when you show just the alpha channel:
thanks for the reply 
for some reason the png I uploaded was converted to a jpeg when I uploaded it…
the alpha channel is there in the original png though because i can see through the layer when i overlay on a map
Ok gotcha. It looks like it’s not 100% transparent, even on the edges, you can see a darker gray on the landscape beneath. You can put a color ramp in your node setup between the Alpha output and the Alpha input. Drag the black handle to the right to increase transparency
thanks - this did the trick, blur is gone!
dope, glad it worked
