I am editing the capacity/speed and in some cases the time and speed of say how long it takes for a tipper to start and stop unloading. Nothing major just number edits, no code changes. Thanks Mike!
As long as you don't need to open up a .i3d file in GE, but only fiddles with numbers or text in .xml files (and also pictures), you don't need to unzip the mod .. Just open the mod with winzip - open the .xml file inside the zipped file (or the picture) - edit what you want - save the edited file - close winzip, and say yes to updating the zip file ..

PS: I'll be looking for a missing "end tag" .. (this one >) often those that are being deleted by accident - and then the mod is halted in the load process .. But you could always look in your log - it nearly always tells you if something is wrong ..
