My first sig

[Aether]

In fact, I had to look up how to put the special brush the C4D or something, and now I kind of jus't put the C4D thingy in my signature, instead of making it a brush or something, like I saw in other vids.
Please help I'm desperate!

C4d's and brushes arn't the same things, you are meant to paste c4d's into your sig. You can find lots of c4d's on the internet. You can get rid of the black background by changing the layers blending mode to for example: linear dodge.
