A scene i'm trying to make includes a hole in the sky that i'd like to have disintegrating edges, as shown here. I should only need one angle on this scene so i don't need something that's pretty from every angle.
Here's what the scene looks like currently, with a filled black circle for the hole.
And here's roughly what it should look like.
I used GIMP's pick and blur filters to do this, but i'm curious to know if there's a good way to get this same effect straight from Blender. What are my options here besides editing the picture every time i update the scene?
Thanks in advance.
I tried this and it kept adding extra faces to the spikier bits. For now i'll stick with GIMP. Thanks anyway.
