This is an update of Danchi's blueprint Resource pack to 1.17.1

This is a resource pack that changes blue and light blue concrete to a blueprint design, perfectly aligned to chunk borders for easy designing and planning.

I suggest using a flatworld with the following settings
32*minecraft:void_air,minecraft:light_blue_concrete;minecraft:plains;

The blueprint textures will only show at heights 0,32,64,96,128,160,192,224,256,288,320.
Optifine currently doesnt support negative height values, but this is planned in the future
(these heights can be modified in the properties files)
