To avoid the problem with the buggy LOD generator I copied a WorldSpace that was nearly empty (FXLightWorldSpace).

When I tried to edit the landscape and to change the texture I got this:

Some textures dissapear in some cells.

Any idea how to fix that?


[edit]: Sometimes the textures in a cell appears again when I put another texture in the cell.

You can only have 6 textures per quad, press I to view / select / delete / replace / the current ones.

Thanks.
That solved it.
