Black squares in terrain

[Xopek]

Good day. I want to transfer tileset from RA to another mode(OpenKrush). I redited everything and copied all the files, and as a result I got black squares between the squares of the terrain, although in theory the snow should be solid. Please tell me what I'm doing wrong and how can I fix it?

Update(7.9.24): I have found that it depends on option
MapGrid:
TileSize: 24,24
From mod.yaml. When i choose right size, squares disappear but other tilesets breaking.
Has Openra option to have different map grids for different tilesets in one mode?

Sorry, it is not possible to mix different grid sizes/tileset sizes within a single mod.
