HEY! great asset but im having an anchoring issue! i attach it using vrcfury to my hip but in certain poses like a squat its just not attached, it doesnt follow properly, is there a specific way to anchor it?
I just got this set up on my main avatar, and it's pretty easy! The concept is that you are constraining the overall positional/spatial movement of the Howl by tying it to the thighs, which are more fixed in their positioning. Without parent constraints, if I crouched down (FBT), the Howl would end up unnaturally low between my legs. With these parent constraints and a customized Weight, you can make these movements more natural.
1. Select the root asset—the entire Wolf's Howl prefab—scroll down its Inspector window, and Add Component > VRC Parent Constraint. The VRC version is more efficient for what we're doing. You can lock the Inspector window to make a lot of this easier.
2. In VRC Parent Constraint settings, click the + sign to add Sources until you have two. Find your thigh bones in your avatars armature; they won't always be labeled thighs, because it depends on the maker (mine say Leg_Upper). Use your left mouse button to click and drag these left and right thighs into the Source Transform fields. It's easier than using the picker dialog.
3. Still in Sources, set a Weight of 0.1 to each thigh as per the commenter above. I did not test what higher values would do.
4. Near the top of the VRC Parent Constraint section, set a Weight between 0 and 1. You can experiment with test builds to find the best value and visual result. For me, this was between 0.3 and 0.4, but it depends on your specific avatar and preferences. A Weight of 1 made the Howl's spatial positioning so static that when I crouched down it immediately became absorbed into my avatar's belly, so I don't think a Weight of 1 will be useful for anyone.
5. Solve in World Space (default). You can test Local Space for a potentially funny result (I'm keeping those screenshots), but you will definitely want it to be World Space.
6. Enable "Is Active" at the top of the VRC Parent Constraint section. You will see all the position/rotation/offset values autofill.
7. Enjoy!
P.S. I'm not an expert, so if anyone else has more input, please share!
