Hello,
how can I get all vertices compound to a bone to export the complete skeletal animation(bones, bones attributes, keyframes, vertices, ploygons, ...) to a file?
I need the compound bone vertices to know which vertices must be animated later in the 3d engine.
Thanks.

If you mean which vertices are affected by the bone algorithm, I don't think this is available. If you just mean the vertex map data you can get it by finding the first restriction tag on the bone, then looking for vertex maps on the objects and read them as VariableTags.

Thanks for the answer.
I will try to reword it. I have a primitive cube with segments (x=15,y=15,z=15). I created 2 bones and scaled them to fit in the cube. Cube with child bone1, bone1  with child bone2. Bone1's fixation is "fix with children". When bone1 is rotated the whole cube rotate. Bone2 deform just the lower part of the cube.
When I export the whole hierarchy to a file, I iterate through the objectlist and export the cube, bone1 and bone2 with their attributes but how do I know which vertices of the cube must transformed when bone2 is rotated?
Do I get this information by the vertex map?
Milkshape3D exports the bones and every vertex owns an index to a bone. When you transformed the bones, you just iterate through the vertex list and get the information how to transform it by the bone index.

If you are using vertex maps, yes. There are other ways for C4D bones to deform objects: by Function (1/r^2, for instance) and 'Limit Range'. These are algorithmic in determining the bones influence thereby requiring a knowledge of the workings of the algorithms.

If I remember correctly, vertex maps can only be used on polygon/point objects. Primitives and such cannot have vertex map tags assigned since there are no 'real' vertices to which the vertex map can be assigned. If Milkshape3D is doing the same, then you'll need to convert the Cube primitive into a polygon object (MakeEditable or 'C' on the keyboard) and then you can assign a vertexmap (etc.).
