Art Advent 10: Baubles

I put a lot of work into the shaders for this one, and I'm pretty proud of them. The glitter shader uses the voronoi color output, projects it onto the normal, and perturbs the normal by that amount in an adjustable way. That took a bit of work, because I initially tried to output an RGB normal map and feed it into a Normal Map node, but I kept having artifacts on UV seams. Skipping UV and tangent space entirely bypassed that.

The bulby node tree (I think of it as a pumpkin) is done in UV space via two sine calculations, one offset from the other by half a period, and taking the max of it. It's a neat effect, and I've enabled a "Y Influence" input for twisting it along the V coordinate and a "Band Number" output to allow alternating colors and other effects. Getting the band number playing nicely with the Y influence took a bit of trial and error, but it's turned out well, I think.

Something new for today. A scene from the Catbird Seat Arcade.

It's the last full moon of the year and I'm jumping back into one of October's daily drawings. Here's my interpretation of iconic The Voyage to the Moon poster.
