I have the format pretty much figured out, I just haven't the foggiest idea on how to convert it to something usable.
Here's some sample animations and a skeleton.
There is already a Blender importer, but it only works for the 2012 version. However, the 2011 and 2013 formats are very similar, so I can't imagine there's a large difference between 2012 and 2013.
The animations use hkaSplineCompressedAnimation. Here's some info we got so far:
Code: Select all
struct __cppobj __declspec(align(8)) hkaSplineCompressedAnimation : hkaAnimation
{
int m_numFrames;
int m_numBlocks;
int m_maxFramesPerBlock;
int m_maskAndQuantizationSize;
float m_blockDuration;
float m_blockInverseDuration;
float m_frameDuration;
hkArray<unsigned int,hkContainerHeapAllocator> m_blockOffsets;
hkArray<unsigned int,hkContainerHeapAllocator> m_floatBlockOffsets;
hkArray<unsigned int,hkContainerHeapAllocator> m_transformOffsets;
hkArray<unsigned int,hkContainerHeapAllocator> m_floatOffsets;
hkArray<unsigned char,hkContainerHeapAllocator> m_data;
int m_endian;
};And if you look at the ASCII example in the link at the top, it corresponds to this part here:
Code: Select all
