To op's situation, i open up m3 and m4 and redo the scene copying the numbers and settings when i run into this issue, yea an export situation would be less time consuming but this is the solution for me and possibly others if no one thought about it, there it is. (export what you can, though)
Just intrested on how many people on here use open canvas, was figuring maybe we could get a few polycounters on a certain night doodling or something? anyone intrested?
