BAD CHUNK SIZE
I think I have found another bug:
Using Imagine 2.9 (Amiga)
Enter detail editor:
Load vtx-2.obj (A spline which was pointized in spline editor)
Select and Sweep with defaults
Save as vtx-2-swept.obj
Load
Reproduceably generates "BAD CHUNK SIZE" Error.
If I do the same with Imagine 2.0 and load it in 2.9 everything is OK.
If you want examples files I can upload…
