Short progress update
After a long time, I was able to continue working again and have almost completed the re-texturing. All that is missing is a crossbar and the main texture is complete. Then I can import the all obj files back into the gr2 files and at the end I only have to adjust the shadow cast by the AO texture for the roof. Because the arrangement of the objects is now different than before.
