Ok, so I have this animated person_holding_gun mesh(md2 file) and want to actually put the gun on his hand. I do can get the current vertex data to get the hand’s vertex position when not animated, but, when the person is animated, the vertex data seems stays unanimated.
So, is there a way to get the vertex data from the animated mesh?

I think the way this works is that you attach the object to the SKELETON’s HAND, not the mesh itself.

I will be facing this issue soon as well and preliminary research seems to be pointing in that direction.

Well, I do think using skeleton based animation will be the best solution considering I need to rotate some body part after animating too…
What is the most convenient way to export to skeleton animation mesh from blender(I’m still using the old 2.49 I believe). I have already tried to use md5 exporter but it seems I missed one step or two and still fail to display the mesh on the screen..
But I do still hope that there is some kind of way to do it using vertex animation since I’m already kind of get a hang of it.

I haven’t tried it, but if I was you, I’d put down index of a chosen vertice, then lookup that vertice’s position and normals at each frame and reposition my object according to it.

Yup, that’s what I’m currently using
I’m using this

to get the vertex position, but it seems that using subgeometries doesn’t take animation into account, so maybe I’m just using the wrong technique.
I do think that the VertexAnimationStates should get the reference to animated vertexData, but I still cant find it.

Oh and I also do applyTransform to put the gun in the world position ( the result was in local position)
