MCEdit Filter to create One-Commands for Minecraft 1.12
This MC Edit Filter allows you to port a selection of blocks into command blocks. This is a filter originally made by Gentlegiant and Xafonyz, I updated it to make it compliant with all the Format changes made in Minecraft 1.12.
Download the zip file and extract into your user MCEdit filters folder located in Documents\MCEdit\Filters.
Once the file is in place it should be available in the filters list in MCEdit.
Please note that this filter is not compatible with previous versions of Minecraft, the JSON formatting is different in 1.12.
For specific instructions watch the video.
