Wrong physics movement direction

[weary sierra]

Hey guys, so basically, i was doing a VRChat .fbx model to convert it into gmod as a ragdoll and then into a playermodel.
So basically, the model is done ive did even the physics but there is a problem, when i want to coordinate the orientation of the physics (in particular the leg) the Z coordinates respect the direction but it doesnt go totally back, it just goes diagonally in the back as you can see in the picture. In some models that i've made, i'venever had this issue, i've even applied the physics to another model with bip_bones and the issue doesnt persist. So, i was just wondering, its normal or the model is messed up? Because this problem only applies on the "bip_hip" bones physics. Any help is appreciate it! Thanks.

As you can see, it doesnt actually goes back but like in a diagonal way.

This persists even in the other coordinates (they go to the right direction ofc but in a diagonal way)

I even moved the leg in blender, it doesnt persist there

Another thing, i noticed that the coordinates are wrong with these bones in fact, if i add another model with bip bones the X coordinates goes foward and backwards, meanwhile this one does not.

“bip_xxxx” bones won’t work for PMs.

“Valvebiped_xxxx” is what Gmod uses for PM and NPC animations.

i always did this for the ragdolls and never had this issue

thats strange

im only doing for the ragdolls

[small barn]

Download the required template.

Do the “Bone rename” section and “QC editing” only.

[small barn]

Then use the $collisionjoint commands from the template QC.

then i rename them into valvebiped for make them into pms

[weary sierra]

im just doing that from hlmv

but the orientation is wrong

only for the hips

[small barn]

Then correct it.

[weary sierra]

i even tried to re do it

[weary sierra]

i did it even at the earlier state

from zero

[weary sierra]

yeah but what i mean is that the coordinates of x are wrong they dont go foward but diagonally

they need to go foward

if you know what i mean

its difficult to explain

[small barn]

I’ve never had an issue like yours in my entire modding career. I’ve ported hundreds of VRC models. But none of them has that issue.

[weary sierra]

do i need to rename the hip bone?

probably it will work? idk

[small barn]

No. It doesn’t matter for now.

[weary sierra]

cause the physics is fine

[small barn]

It's just bone orientation.

[weary sierra]

so you think its normal?

[small barn]

Absolutely not.

[weary sierra]

its like that it doesnt recognize that its a hip bone and when i use the x coordinates it doesnt go foward

[weary sierra]

same idk why it happens now

[small barn]

It's fine as long as you specified the bone name correctly + hips bone is the root of the model’s armature.

[weary sierra]

probably i rotate the hip bone by mistake while rename it?

[weary sierra]

yeah they are connected to the pelvis bone

[small barn]

¯_(ツ)_/¯

[weary sierra]

if you want i show what i mean

wait a min

This is another model that i converted it from MMD. As you can see the X coordinate is correct

and it goes foward

meanwhile the new one it isnt

it goes diagonally

and the coordinates are random

[small barn]

Compare that MMD model’s bone orientation and your current model’s bone orientation in Blender and match it if it differs.

[weary sierra]

meanwhile the other bones work fine

[weary sierra]

you mean the roation?

*rotation

[small barn]

Yes.

[weary sierra]

how i supposed to do it? cause its difficult to re adjust it

cause when i rotate the bone idk if its correct or not

you know what? ill re do it from zero in another folder

one time happened that the model didnt even find the texture because for a location folder

thanks anyway tho : )

[small barn]

Use my guide if you decided to do it from zero again.

It’ll worth the time.

Plus, it is all in one: Ragdoll, NPCs, and PM in a single run.

[weary sierra]

oh wait you are that guy from that guide?

you helped me so much for some things

like for the errors

i watched your guide 2 months ago

[weary sierra]

Update: Its the model it self

i did a new model from a random mmd model to see if it was me transforming badly the model, but then i rename it into bip bones, compiled it and the coordinates are correct. So basically, it was the model it self that it needs to have some particular changes.

I probably need to re do it and be careful without moving the the bones

Thank god, i thought it was me not remembering how to do models

haha thanks anyway

[small barn]

Oh. That's weird, haha.

[weary sierra]

Yeah, in fact later i need to check cause if i need to do something i need to resolve it, this is how my head works haha. Some models that had problems like that i left the project of them, since source is crap sometimes.

Im good at models now so i got panicated after i noticed this problem
