Hi everyone. I wrote a shader that involves creating a dynamically changing color gradient effect, but now, I want to make the edges of the shader fade out with transparency effect. The current shader looks like this:
How can i do so in shader graph??? All four edges of the shader should be transparent btw, i just took a screenshot of a portion of the reference, which makes the left edge not have the fade out effect when it should. Thanks in advance.
Maybe it’s time to dig out the Shader Graph manual?
You could use any number of ways available to generate an alpha channel, which then fades your texture away on the UV edges. You could generate this alpha using a texture mask you create in your art app (like Photoshop) or generate the mask procedurally inside Shader Graph. One very simple way would be to measure the distance to the center of the UVs, then maybe adjust it with pow function to make the fall off different, or use smoothstep.
Here’s a quick example I made. You can take it further from here by modulating the mask edges with noise etc., making it maybe more like a cubic falloff etc. But it should give you an idea.
Just wanted to say thank you. I had been messing around with my pre-existing shader for hours to get an effect like this. This was really helpful. Thank you
