4.0.0-alpha+main.2aa393e72771Short description of error
When exporting a curve that has a depth value above 0, the output .obj file will contain multiple objects overlapping each other.
Issue only seems to occur in the new .OBJ export. Cannot reproduce in the Legacy one.
Attempted various combinations of "Grouping" export settings, but issue persists.
Exact steps for others to reproduce the error
You can also import the .obj and see that multiple objects are created.
(example below where I have moved the edges to show the second cylinder)
Hi, thanks for the report. I can confirm. This is happening since new c++ obj exporter was added.
I believe this is related to #112885 / #94038 where depsgraph iterates the curve twice (maybe original curve and evaluated curve with beveled vertices).
