Hey people! I am looking for a way to create a blur material. Now, I don’t want the texture itself to be blurry - I want from the borders of texture to the rest of the level a 100% to 0% opacity colour. Think of it as an emissive black colour. How can I create such effect in Unreal?
Blur is not something you can make without a background (it’s a filter). I only think this is possible with a custom expression node due to limitations like the ability to have for loops in the node editor.
Your post is a bit unclear.
Are you wanting blurred edges of the screen? Are you wanting an opacity change on a texture in the world?
A vignette effect?
Something else?
I want an effect, similar to this : http://pe-images.s3.amazonaws.com/photo-effects/outline/photoshop-outer-glow.jpg
I want the blur to act as an outliner of the said mesh, which is always facing the character, but I want the line to have a feather effect - 100% opacity near the mesh and going down the further away from the mesh the outline is.
Edit : I know there’s the ‘emission’ color which does exactly that, but I want the emissive color to be black, so it won’t work that way.
