After some test i found out that EBE is a great tool and easy to use the ablility to put your custom textures is great for crating the basis strucure for building after finishing with the EBE you can add entityes here and there to make it more detailed.
But i found one problem the single wall is too short its like 20 cm above human head you can ofcourse add rows to heighten up the strucure but this repeats the texture and if for example you have a wall texture thats not tileble verticaly(like half of the walll is tiles and the other hal is plaster)this couses a a problem and beleve me the best wall textures are not tileble.
So lee is it posible lets say to make walls and floors that are 140x140 units high and the texture dont repeat it self.
in curent state a single floor is way to short.
Also i dont know how difficult this might be it will be extremly helpfull to add a feature to change the grid size(not in the EBE in the editor grid)
