maybe use lego worlds and import the terrain?

Thanks for the program, I didn't know it
Unfortunately, as usual it only work on windows
Not in osx or linux

On LEGO Worlds, I managed to export landscape in .lxfml format
But in general they re too heavy to be imported (35-40 mo for a part of a cliff)
lego designer, studio, or leocad can import it but with 70 000 pieces at least
It 's hours for trying cleaning 64x64 (I think) landscape, and I don't know if I will be able to Import it in Mecabricks

Mecabricks was incapable to import this kind of heavy file

The others objects (plants, flowers, trunks, animals) aren't in the .lxfml files and you had to re-create all of then

Smaller files. are imported well

Some plants, trunks and elements, some inspire by lego world decoration

On blender i'll try this addon : https://www.blendermarket.com/products/bricker

You can transform 3d object into bricks.

ya I have that addon

its free on his github!

It is free on github as all python code for Blender is. But remember that this guy is working his ass off to produce a great tool and therefore I would always encourage people to buy it, especially if you like and use it.

I bought it this week

I'll try it as soon as possible (I had to render some blender render of a watermill project)
