# Dimensional Structure Restrict<\/p>\n
DimStructRestrict is a lightweight Minecraft Forge mod for **Minecraft 1.20.1** that allows you to **control where structures can spawn** based on dimension and structure rules. Designed and developed by **Troy Cook (@cookta2012)**, this mod provides fine-grained control over world generation behavior \u2014 especially useful for modpack developers and world designers.<\/p>\n
Initial release will be 1.20.1 other versions will be coming later.<\/p>\n
