Quoting original commit log:
This patch fixes 2 issues with the vmap extractor. 1) Incorrectly converts vertex coordinates. 2) Forgets to convert coordinates on triangle indices.
The effects of [1] causes models to be flipped. This isn't very noticeable on most trees as flipping a cylinder results in the same cylinder, but it's very noticeable on any non-symmetrical geometry (which, even includes trees, it's just harder to notice). [2] Didn't seem to be a problem when the coordinates were incorrectly converted, but when applying the correct conversion caused some triangles to be flipped (i.e. facing inwards).
You will need to re-extract vmaps and re-generate mmaps for these changes to take effect.
Fixes#417
-Fix warnings from -Woverflow on implicit constant conversion.
-Fix warnings from -pedantic.
-Fix warnings from -pedantic.
-Fix warnings from -Wformat.
Two minor changes in addition :
-Replace a defined value equal to 2^31 - 1 by std::numeric_limits<int>::max().
-Remove useless null-check on pointer returned by new. New doesn't returns nullptr on failure, it throws std::bad_alloc.
Increase the max walkable angle and max walkable climb in MMAPs generator to allow NPCs to jump on fences and climb steps.
This requires MMAPs to be extracted again with mmaps_generator, old extracted MMAPs are still compatible but will not provide the benefits of this commit.
Fixes#9965
Fix not-NULL terminated char buffer and uninitialized memory written to vmaps due to WMOLiquidHeader struct padding bytes left uninitialized. The padding bytes should be ignored anyway by VMAP Assembler so no re-extraction is required.
