Note. I had some difficulty doing that with some images even after repeated use of ungroup. I ended up just going into the SVG file and deleting all the groups. This usually happens if there are filters in place. Removing all the g tags but keeping the paths inside the groups in the SVG in a text editor might be faster than cleaning up in Inkscape.
Also, some paths might be worth eliminating altogether. In order to get a better idea of what it'll look like, try: View->Display Mode->Outline. To simulate occluding, you can try combining individual paths first, and using union to combine into larger groups. This takes a bit more work. If it still doesn't look right, you're going to have to go in and delete nodes, and generally rework the shape to simulate occlusion.

3) Click on the path, and choose dimensions for W and H that would look good in the game (no more than 4096 for W and 2048 for H). The Lock button may be helpful here. Generally resize it and reposition it using the document white area as a guide to how it will look on the in-game drawing area, then save and quit.

5) Open the file in Inkscape again, Click on the path again, then go to Extensions->Modify Path->Flatten Beziers and flatten out the curves to your taste. Default of 10 seems fine most of the time, but for small curved objects you might want something like 5. Keep in mind, the more the approximation, the more points that Hedgewars has to draw, which can be rough on the engine and network communication, then save and quit.
6) Edit the file, and delete everything but the path data. You should have a one-line file starting with something like M1234.3 456.78L3298.3 9023.34 and so on.

Since this page is a mass of hacks, here's one more redundancy reducer, in bash this time.
