Tileset "always on bottom"?


Is there any way to make one 3d-tileset appear on bottom of every other tileset no matter how the depth-position is?

I quess what I am looking for would be a way to clear depth buffer somehow in the middle of tileset rendering passes? Do we have something like “render tilesets in multiple passes”?

Another way to achieve this would propably be eyeOffset for tileset, just like we can do with billboards…?
