I created an Advent Calendar this year for our Xmas event. The model is comprised of many existing assets with some new ones added on top. As it features 10 of our in-game crates, it would have been far too high-poly and have too many draw calls to leave as-is, so I created much reduced tri-count boxes and baked everything down in Marmoset Toolbag in to one new texture set. This also enabled me to paint on the Advent Calendar numbers and bake out a unique AO map. I cloth simmed some tartan fabric and added some tinsel and lights to make it a bit more festive.
