Started over and now have all the models and groups set in the new sequence before I start the import. Created my map file. Imported the effects, did a save and played it.
A couple of issues.
1. How do I import a copy of the timing track? Or if there was a lyric track how would I import that? I would hope/prefer they come across automatically. They can easily be deleted after the import if I do not want or need them.
2. The P10 matrix on the donor sequence has 3 layers, but the import only brought in the first two.
3. For some reason the text effects on the matrix did not import right and when I clicked on one to see if I could fix it I got a whole bunch of error statements to the effect that slider?

was not found. After clicking ok thru all the errors I was able to go in and recreate the text effect. I had the donor sequence open in its own folder at the same time on another monitor so I could see both the original donor sequence and the imported sequence.
3. The donor megatree has effects that start right at the 0 sec mark. The import effects start at the 10 sec mark and are not the same starting point of the donor 10 sec mark in addition to missing all the effects that were in the donor sequence in the first 10 secs.
4. Other effects on other models are not coming across at the right time frame as the donor sequence.
5. Another usability issue I found is that after I select the donor model/group the selection window dropdown closes, but the selection is changed when I use the mouse wheel to move to another model to select. Found that one by accident as I didn't notice the scroll by mouse wheel until selections were changed and I had to go back and reselect.
There may be other issues that I just have not uncovered yet as these first couple are big and glaring.
These sequences are updates of the same ones that were used in my last years show, but with some new props added and some effects changed. I am starting with a totally blank sequence with only the groups and models shown. I have imported a lot of sequences last year and wrote the oriiginal procedure that is in the manual so I am not a novice at doing imports, but I can make mistakes. I just can't see them at this state. Fortunately it is not crunch time yet. I can provide the files needed, but prefer not to post them publicly at this point as I am not the creator of the donor sequence although it was done by a friend of mine whose sequence I used last year without issue.
