Trail Renderer

Hello guys, i have a problem with the trail renderer. When i use use black as one of the 5 colors it comes out as transparent (no black at all). How can i fix it? I have also the alpha setting to 1 (visible).

You’ll need to put a material so it could have a color. You can make an image that is black and make a material of it. You could then put it to the material of your trail renderer.

Thank you, i have already used different materials (not black). Is that my fault? If i use black material will i have problems with the other colors?

Ok got it. So the image must be just a black square? Of what dimensions?
