it was made with blender you tube just likes to add that when you use the video editor,
It was made in blender, with some filters applied by youtube and I used there editor to stitch a few videos together
I really enjoy these, they’re very calming to me for some reason, even the flashes of bright colors that transition between the animations are nice. Have you ever thought about trying to match the movements in these animations with music?
