Hi Valentin, there is no such limit. The polygon can be very complex. Splitter just uses a different algo if this happens. The problem here is that splitter tries to find rectangles that fit into the polygon AND don't have more than the given nodes AND are not too empty AND they have to be on the selected raster. The more complex the polygon the less likely it is to find a solution for this. You can change the limit in the source and try what happens.

Earlier, I also wanted to use the --polygon-file Splitter option, but found it unusable. Only 40 vertices are allowed in the poly file. This is extremely small for repeating the border for a background polygon. Why this restriction? Very lacking the ability of unlimited poly file!
