I made another paper texture for CSP using rainbow noise! this one is a little more organically textured than the other one and suits rendered art really well.

to use, download the asset to your CSP materials folder, then just drag and drop onto your canvas. I recommend lowering the opacity to around 35% and turning the layer mode to Overlay for best results! it can be scaled to any size so adjust it to fit your resolution.
