I am having major rendering issues (or so I thought) with DarkRadiant, the latest source build and the 0.10.0 build on Sourceforge. I've spent the last few weeks reinstalling driver after driver. Well today I finally figured out what's going on; As you can see from the screenshot, the light entities origin and light center are different. I don't know when this happened but if I create a new map and add a light that's not at 0,0,0, then it's light center is at 0,0,0 while it's origin may be at 1000,1000,1000 (just for example). Now I'm screwed as all the lights in my map have had their centers changed to 0,0,0, so none of them illuminate ANYTHING. If I manually change the light centers to equal what's in the light origin, then the light works correctly. If I take that light entity and drag it it's light center fields aren't updated and the further the light entity is dragged, the less it illuminates. Can anyone help me here? Greebo maybe? I'm wringing my hands here thinking about how much work it's going to be to replace all my lights in all my maps as each one has been opened and had their light centers corrupted with 0,0,0,
