Step 1: Upload Your JSON File
Click or drag your Object Spawner JSON into the upload area. The file must contain an Objects array. Structure objects are used as anchors, while nearby non-structure objects become CE points inside those structures.
Step 2: Configure Your Group
Select or enter a building class only when the JSON does not include a detectable structure anchor. Choose whether the generated group should replace vanilla points or add onto the built-in vanilla point set. Categories, tags, and usages fall back to the built-in vanilla group when left unselected.
Step 3: Convert and Review
Click the Convert to MapGroupProto button. The tool generates a schema-valid <prototype> snippet containing one or more structure <group> blocks. Replacement mode emits only the new CE points. Add-on mode keeps the built-in vanilla points for that structure and appends the new CE points into the selected container.
