Summary0004767: Re-exporting .ase models screws up their normals
DescriptionExporting an .ase model from the "Export selected as model" DR option that has an .ase model func_static (alone or alongside brushes, patches, etc.) in it will cause the then-new exported model have its normals screwed up UNLESS the func_static's orientation aligns with the world orientation.
Steps To ReproduceCreate model, eg. models/darkmod/architecture/chimneys/chimney_metal_pipe_tall.ase

Make sure the func_static aligns with world directions -- Y is up, X is right in top orthoview.

Select it, Export selected as model, choose .ase.

Note that it looks fine in-game under light.

Now rotate the func_static 90 or 180° so that it no longer aligns to world. Re-export.

Reload models in-game, note how the normal has been reversed and now the model is dark when in light.
TagsNo tags attached.

Confirmed, its most notable on existing cylindrical models (pipes etc)

Tried the above steps, but I can't reproduce this - maybe it's a combination of the export settings and the model plus the sequence.

Can you give me the settings you're using to export the model?
Also, can you confirm, that a DMAP run is not fixing the problem?

Nevermind, I was testing with my intermediate WIP code, which had a different problem overshadowing this one. I can confirm it now, and I know what the reason is.
