Hi Ominae392,

Thanks for removing that!

The reason why .hkx files are much faster is that they can be saved as platform-specific binary files and then loaded straight into memory. No parsing of vertices or construction of geometry is necessary, just a memcpy().

hkLoader is used in most of the animation demos but not many of the physics demos, as most of the geometry for the physics demos is loaded at runtime. However, hkBinaryPackfileReader (which is used by hkLoader) is used in a few that you can see. Have a look at Physics/UseCase/AssetStreaming and PhysicsApiCollideShapesLandscapeChunkMopp. A pretty simple one which loads a .hkx into a buffer is here: CommonApiSerializeNativePackfileLoadNativePackfileLoadDemo.cpp.

Let me know if you have any questions about hkLoader or hkBinaryPackfileReader.
