Since I updated the exporter to export for SR 3.0, I can't import meshes at all, even meshes from 2.8, which worked perfectly, before I updated to the 3.0 exporter
I get the same error, no matter if it is from SR 3.0 or 2.8
While generally I try tu use blend files, there are some cases, where there is only a mesh file.
In my case now I want to import the cave models, I made a long time ago (to rework these, improving UVs, find or pick better textures, or create new variants)
I recently sorted the blend files, but for these I didn't find any. Actually when I made objects for 2.8 I often imported meshes where I didn't find a blend file, including the crystals and rocks, when I made anomaly version.
You also said something about converting mesh files to xml files, how do I do that, if I need that? I never done that before, only imported directly from blenders import menu.
I also doesn't matter right now, if I get it to work to import the newer or older mesh files, especially when I need it for older objects without blend files. For newer I now always keep and upload them, that I don't need to do it.
In case I won't get the importer to work, I will just start doing new cave elements from scratch, though then there is definitly some replacement work needed. With importing I can get the rough shapes right and textures, so that it looks quite to the old, that everything should be fine, maybe checking some tracks, where cave tiles are used, if I see something.
