Pixel art trail renderer

Hi, so I’m trying to create a pixel art style game, and Im having trouble with the trail renderer, which is a vital part of the game. The sleek and smooth look of the trailer doesnt match the rest of my game, is there anyway to get it to be a bit more pixelly?

I’ve not used it, but you could try setting the texture you’re using to have a filter mode of ‘point’. This stops the renderer nicely blurring the pixels, so a small texture will look very blocky.
