Hi everyone,
I’m reaching out to ask for your help. I’m trying to use Dragonfly following the technique mentioned in this forum post: Dragonfly Unable to Apply Custom ConstructionSet. However, I’m running into some issues.
Despite changing several materials, I haven’t noticed any difference in the temperature results. I’ve attached my JSON file here.
If anyone could help me figure out what’s going wrong or point out if I’ve made a mistake, I’d greatly appreciPreformatted text
ate it!
Thank you all so much—this community is the best!
