The Thermal Series is undoubtedly one of the most relevant mod techs for the modding community.
One of the mod's classic mechanics is the ducts, connectors that can interact with fluids, items, and energy with the aid of attachments, a mechanic that has been reworked in the mod's most recent versions.
The Dynamiducts mod reintroduces ducts and attachments to version 1.21.1 – a version that, until now, hasn't received an official Thermal Series update. However, the assets are still the old ones, those used in versions 1.7 / 1.12.
The project fixes exactly that! Adding new assets for the items added to the mod.
