[Theory]

I'm just starting to get a feel for ZH modding, but I'm having an issue and hoping someone can tell me what I'm doing wrong.

I've been following the "Infantry Modelling" tutorial here,
and have successfully edited AIRNGR_SKN.W3D and seen my model in the game. However, it no longer animates when running, it just glides around with its arms sticking straight out.

To fix this, I've been trying to modify AIRNGR_RNA.W3D. However, every time I try to bind the skin to the skeleton in RenX so I can see what I'm doing, I get a "Cannot bind: would create dependency loop" error.

Here's my steps: starting from scratch, I import AIRNGR_RNA and hide all. Then I import AIRNGR_SKN, hide the model, and delete everything else. Then I unhide all, select AIRNGR_SKN, and clone it to AIRNGR_SKN02. Then I delete AIRNGR_SKN. I create a westwood space warp and add all of the bones to it, then try to bind AIRNGR_SKN02 to the space warp. That's when I get the dependency error.

Am I doing this totally wrong, or am I just missing something obvious? My goal is just to bind the skin to the skeleton while I'm tweaking the animation so I can see what's going on.

P.S. One other question - the tutorial seems to indicate that if I haven't modified any animations, I should see the normal ranger animations but have my second gun incorrectly floating in the air. What I'm seeing is that the model doesn't animate at all. Does that mean I've screwed up one of the files? If so, which one (skin or skeleton) is the likely culprit? Thanks for any help!
