when i register a node (block) for a minetest mod i can set for every side of the cube a image
=> tiles_images (top ,ground, back,front, right, left) thats easy to find out.
is there a source i can read abt the other parameters ?
for example what's the purpose of
is_ground_content =true/false
second: whats abt the Transparency of the cube images? it only shows the front view of the image to the cube. so when i have a half cube i can see that from the front as half cube, when i look from the back i cant see anything as i would look thru air...
is there a workaround to solve such problem. if yes, that would be a good way to create easy furniture or other 3-d like things in minetest.
edit
a picture for better understandig

or whats worse
