Hi.
i dont know if this is where i should post this...
if you think it is somewhere else. plz move it...

So, i am looking for such tools:

i need to place something in the pond very close to its surface, so people can walk on water.

and i need to break this wall to open the view at an orange orchard, yet my professor says that we must place a transparent material instead of the wall so orange debris ont fall and spoil the archeology...
Do you guys know any about these stuff...
i cant seem to find anything, basically because i dont know what they call them...
