Summary	0004767: Re-exporting .ase models screws up their normals
Description	Exporting 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 Reproduce	Create 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.
Tags	No tags attached.

greebo 29.04.2018 03:54 administrator ~0010410	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?

greebo 30.04.2018 04:14 administrator ~0010422	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.
