I followed your directions from another topic:
Perhaps this wasn’t the way to go, I am very tight time scheduled so I try to find solutions myself while waiting for replies.
I tried re-importing it into nomad as well, and that crashes. I have now re-created the entire thing so I guess this can be considered solved, the crash has been very frequent when I use “Simple merge” on too many meshes at once, even though they are very few vertices and the project is very small, it seems my iPad cannot handle the merge process very well.
I will be more cautious in the future and try to save a back-up project before merging larger amounts of meshes.
Thank you for your help and this wonderful app!
