Why do you expect them to be different?

that's what i was wondering... when i calculated them ingame they were only aligning for some models... when i check in studiomdl the idle animation of both models ( modelviewer csgo:sdk ) bones LOOK different. but perhaps that derives from the animation.

i am trying to calculate the current boneposition of a player. but i don't want to go through reading the animation sequence data, keep track of it and then recalculate the current bone position for each tick from that....

isn't there some function exposed for this from within the game ? ( getting current bone positions )

I think the default bone positions are not their idling stance, but their T pose they get when they hold no weapons

with "idle" i meant "default" in the sequence tab of SDK.

i think the problem is that in my code i am just reading default mdl file bone positions... not "in world" bones positions...

but with the link : i am not looking to get the weapon muzzle flash position. i know how to workaround that... i was wondering if the engine had a way to access all active current bones positions. i think "CBaseAnimating::GetBoneTransform" looks like the right approach. as you suggested taking into account animations... did that code work?

header = player.model_header

    for index in range(header.bones_count):
        if header.get_bone(index).name == 'ValveBiped.Bip01_R_Hand':
            break
    else:
        return

    GetBoneTransform = player.make_virtual_function(
        199, Convention.THISCALL, [DataType.POINTER, DataType.INT, DataType.POINTER],
        DataType.VOID)

    matrix = Matrix3x4()
    GetBoneTransform(player, index, matrix)

    matrix.position # current position of the player's hand bone
