fixed point?

Oh, you just posted :LUL:

adrientd

That's the actual question :LUL:

adrientd

What's especially interesting is that apparently 16-bit floating numbers were only added to IEEE 754 in a 2008 revision, which is too recent for a 2003 game :FulliautomatixBruhL:

Old emoji xD

pegperegogaucho

Maybe the author assumed it would be a 16 bit float or whatever

pegperegogaucho

anyways I found the compression code for the keyframe somewhere on github some time ago

adrientd

Yeah, could be interesting, but it might also be straight forward, just need to know how many bits is the fractional part

adrientd

Oh yeah, just had to check the older Max plugin referenced in the Blender plugin's readme, it seems to handle the 16 bit numbers correctly.

pegperegogaucho

lol, I just found the exact same code on xentax

adrientd

So it seems to be a floating point number, but from the code the mask of the exponent being 0x7800 means there are 4 bits for the exponent, whereas for IEEE 754 it is 5 bits.

Now I have compressed animations working 😏

adrientd

I fixed the plugin to correctly decode the 16-bit floating point numbers

adrientd

I pushed the changes into a fork: https://github.com/AdrienTD/Blender-3D-RW-Anm-plugin

Zip file with the fixed plugin:

👏

pegperegogaucho

You should fix the plugin to add support for multiple file import

adrientd

Yeah I noticed when you import an animation to an armature and then import another animation, it will remove the previous one.

pegperegogaucho

You can change the current animation using the action editor
