My girlfriend asked the other day if I could make a new background for her phone so I made this tribute to cubes and cartoon purpleness. If lazily intersecting geometry makes you cringe then it’s probably not for you but otherwise feel free to use it yourself if you want a change of background for a bit. Modelled in blender using mainly particles and rendered in Cycles using mainly trial and error. Bit of post-pro in Gimp.
Alvarocgi yes the cubes use a simple diffuse shader, but the colour is made slightly different for each instance by using an Object Info node and colour ramp - connecting the ‘Random’ output to the ramp makes each object take a different colour on the gradient. There’s also a Layer Weight node being used to lighten the edges of the cubes by using the ‘facing’ value to mix with a lighter colour. I’ve attached an image of the nodes so you can see (this is for the pink central cubes. The others use a more blue/purple colour ramp).
(The scene’s pretty messy but should make sense eventually. Most of the background is in layer 1, the camera in layer 2 and the pink cubes in layer 4 as this made them easier to work with, so make sure these layers are selected before rendering)
If anyone does anything interesting with this please post the result here as I’d love to see what you come up with.
