I have been meaning to study Particle's recolorable scenery pieces and see how they work. Back when we were testing ZT Studio I was never quite able to wrap my head around that.
A little update on the windmill design:
Going to try to wrap up my two things for this pack and the backstage pack before I continue my mexico pack escapades. I had a moment of clarity the other day when I realized I was creating things but not releasing them lol.
