I had noticed a lack of sand stuff in Minetest. There is sandstone and things for normal sand (aka beach sand), but not desert sand? What? And then there is silver sand (new to Minetest as of 0.4.15), which doesn't have sandstone and things either (although that's not suprising since it's new)*. So you might have guessed by now what this mod is for. I present to you:
Sandplus
This mod adds:
-Desert Sandstone
-Desert Sandstone Block
-Desert Sandstone Brick
-Silver Sandstone
-Silver Sandstone Block
-Silver Sandstone Brick
-Stairs/Slabs of all listed above
Crafting recipes are the same as normal sand things, but with desert sand and silver sand instead.
If Technic is enabled, all recipes will be replaced with grinder/compressor.
Screeny Shots! (I used the greenscreen mod btw...)
