I did delete the .RSR file when using the remapped file (the one with the same name as the original). For the new versions, I had renamed them and changed references to the original in existing .CR2's to the new name and directory. I made sure everything was the same case and that I had the right directory (in my case ../Runtime/Geometries/Revelation - no go. If I recall correctly, I got an error message saying C Exception Handler or something like that. The remapped version works perfectly when I replace the original with it (renaming the orignal to preserve it). Is there any other line in the CR2 that I need to look at other than figureResFile?
