I found a different rocket launcher viewmesh and pickup (.lwo) but it doesn't seem to have come with a worldmesh. Since the new design is just a slight revision of the old, I'm wondering if it's possible to simply swap the original worldmesh geometry with that of the .lwo file while keeping the skeleton intact.
This appears to be esoteric today. I had a similar question that will likely go unanswered regarding conversion of .LWO files. I can turn them into PNGs in reaconverter, but if I wanted to increase their resolution what would be the valid path? Does anyone know?
It looks like I will need industry software, and wouldnt it be nice to have confirmation that I was getting the right thing. For all I know the support is deprecated.
