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. -2) Go to File->Document Properties and specify 4096 for W and 2048 for H.
