Hello,
I’m using the free version of Unity (4.6.5) and I want to know if it is possible to create glowing circles like in this example with a free Unity version. And if so, then please let me know where I have to start.
I don’t want to draw those circles with tools like Illustrator or something else. It would be cool if I could do it by scripts + shader (maybe particles, too?). Is it possible?
Regards,
wax
Yes, find a circle shader and modify it. All you need in the fragment shader is to find the distance from a texture coordinate to the coordinate 0,0, using like sqrt((t.xt.x)+(t.yt.y)) sort of thing. Then using a couple other functions to limit the range of the output and make it softer etc… there may even already be a hollow circle shader out there that you can use. Then it will look great no matter what scale.
