backgrounds

Hi I need some help! I’m thinking about making my own 3D background. I have read up on how to do it and know it will take time so that’s no worry, I’m also thinking about putting a sand fall (waterfall) in. I have been reading for a while how to do it so quite confident it doing it all however...
