problem was in incorret calculatiing boundingbox. I think I solved this problem, in CSkinnedMesh.cpp:
Code: Select all
void CSkinnedMesh::finalize()
{
u32 i;
LastAnimatedFrame=-1;
LastSkinnedFrame=-1;
//calculate bounding box
for (i=0; i<LocalBuffers.size(); ++i)
{
LocalBuffers[i]->recalculateBoundingBox();
}
if (AllJoints.size() || RootJoints.size())
{
// populate AllJoints or RootJoints, depending on which is empty
if (!RootJoints.size())
{
for(u32 CheckingIdx=0; CheckingIdx < AllJoints.size(); ++CheckingIdx)
{
bool foundParent=false;
for(i=0; i < AllJoints.size(); ++i)
{
for(u32 n=0; n < AllJoints[i]->Children.size(); ++n)
{
if (AllJoints[i]->Children[n] == AllJoints[CheckingIdx])
foundParent=true;
}
}
if (!foundParent)
RootJoints.push_back(AllJoints[CheckingIdx]);
}
}
else
{
AllJoints=RootJoints;
}
}
for(i=0; i < AllJoints.size(); ++i)
{
AllJoints[i]->UseAnimationFrom=AllJoints[i];
}
//Set array sizes...
for (i=0; i<LocalBuffers.size(); ++i)
{
Vertices_Moved.push_back( core::array<bool>() );
Vertices_Moved[i].set_used(LocalBuffers[i]->getVertexCount());
}
//Todo: optimise keys here...
checkForAnimation();
if (HasAnimation)
{
//--- optimize and check keyframes ---
for(i=0;i<AllJoints.size();++i)
{
core::array<SPositionKey> &PositionKeys =AllJoints[i]->PositionKeys;
core::array<SScaleKey> &ScaleKeys = AllJoints[i]->ScaleKeys;

if (PositionKeys.size()>2)

}
}
