Notes
~0007516 abma (administrator) 2011-11-06 20:29	what to do with assimp releated bugs like this one?

~0007517 Kloot (developer) 2011-11-06 21:11	imo: write an as-minimalistic-as-possible patch/workaround (or failing that, disable the crashing format(s) entirely in the loader), and strongly advice the assimp developers to test their code more.

~0007592 spliff (reporter) 2011-11-13 01:07	Blender support is very alpha quality in the assimp version used by spring. At the time blender support was less than a month old and patches were being added to assimp almost daily. Do you get the error with other formats? If not the only real solution to this is to let blender support mature and pull in a new version of assimp or we can disable calculating tangents in the assimp post process options.

~0007593 abma (administrator) 2011-11-13 01:59 Last edited: 2011-11-13 02:05	i follow the assimp development, but they made no fixes to blender. last merge with assimp was about 3 months ago: https://github.com/spring/spring/commits/02d5469ebf86e46c1643a77eb8ad831aba516ed6 the assimp repo is a bit newer but it contains no useful fixes, so i didn't merge into spring... ( https://github.com/spring/assimp ) only thing they did is, they increased priority for my bug report, see also: https://sourceforge.net/tracker/?func=detail&aid=3385430&group_id=226462&atid=1067632

~0010650 jK (developer) 2013-05-06 00:39	deactivated SigNaNs in Assimp for now
