Thanks. Seem a bit high but hopefully the LOD tri count is much less.

good I found the old blender file again. tris-info see above

Tris?

Of course, I experimented with them and you can even push them into each other to make whole tunnel mazes! xD Would probably look strange on a slope though. It's almost always too steep for anything? Someone should make a sad lovesong about this...

could you do a ploppable verison - would be good to plop some of these around farmland in-game :)
