how do i play the animation

Ragdoll For some a SM64 Machinima idea, But I back to the game and seems back working (i don't know how too)
But thanks for the help any way c:

The errors are related to model scale. For a workaround, go to the Properties menu, located in the SMH menu on the bottom right between "Record" and "Save." Where you see the timelines, open any of them, and select the "Model scale" checkbox.
What type of entity (ragdoll, physics prop, etc.) are you animating? I think I've come across this error consistently before, but I haven't looked into it until now

Yo
having some Lua problems
I am damn noob in this game
someone can help?

yeah Im blind lol I saw the localize phy bones option in the menu and my brain just fused the two together thank you

do you happen to have "don't animate physbones" checked in the settings

All of a sudden the mod flat out doesn't animate ragdolls anymore. I was posing a model I went to change the frames and recorded and i went to playback the motion by scrolling through the timeline but the model didn't move at all and I've tried to actually play the motion but again nothing. I've changed maps, I've tried using props; and those were fine, I've restarted my computer, but its doesn't work anymore and its just ragdolls that don't move. I'm wondering is there a fix i can do on my end or is it just over cause there's a project i was making and i really wanted to continue it.

Having the menu open (either by holding the button or toggling it open from console by typing +smh_menu in console) blocks keybinds. Keybinds only work when the menu is closed. There's not really anything that can be done about it now

For whatever reason my binds like f1 as record dont function while I have the menu held open

make it have you can animated separated parts of the Ragdoll

At this point the only thing i can still think of is making it possible to animate bonemerged props.

thats the one way i can imagine you could still improve this.

are you loading it on the proper entities? you have to load it on the same models you used before, unless you were using some sort of tf2 physics override addons and those suddenly disappeared, which can mess up the bone orders and confuse smh which may lead to errors like this

I had animated a scene and after starting the same map and loading my save it only shows 2 frames and here is the error that is showing;

thank you so much i can now learn how to animate for videos!

I had edited it so uhhh thank you dim sum un :)

As in you cannot find the ~ key, or the ability to open the console with ~ hasn't been bound? It should be below your Esc key or next to the "1" key. Once you find it, you can just press it in the main menu or in any GMod game, and it should open up. If you do not have the ~ key, you can go to your Keyboard settings, scroll all the way down, and find the option that says "Toggle developer console": click that and click "Edit key" to set it to whatever key that you wish to open the developer console

I don't have the ~ keybind (I typed it bc I copied it off the comment from dim sum un)

See here . While the Advanced keyboard settings were removed from the game, the developer console keybind is always enabled by default: just need to press the `/~ button

It doesn't say the 'advanced keyboard' when I have it, how do I get it?

bind b +smh_menu bind n +smh_playback

yeah no this mod doesnt work as of march 2025, hasnt worked since. yes ive tried disabling/uninstalling all other addons but nope, this mod is completely broken now.

im waiting for a fixed version to be uploaded, or this one to be updated.

So far, there are a few Github forks of Stop Motion Helper (SMH) that have this implemented:

- This fork [github.com], made by smg4tech, implements an audio track feature into SMH. Many of the forks bulleted below use this fork.
- This one fork [github.com] simply merges the audio fork above with an 8-month-year-old version of SMH (on Github, not workshop)
- This fork [github.com] (made by me) has the same audio feature too, plus waveforms to allow one to see the peaks of an audio clip over time. While unofficial, I also keep this up-to-date when possible

There isn't a definite timeline as to when an audio track feature would be implemented into the workshop. If you're interested in the unofficial "bleeding edge" of SMH, I'd suggest trying one of these out

one feature that I think would be cool is adding an audio track feature so I can put custom audios when I animate to help lip sync

I can't even get to the advanced options to bind any of the functions that this requires me to. This really needs to be updated.

@Male07 you have to add the +

Unknown command: smh_menu (x2)

how do I bind it

SMH will be gold if you could select one or more keyframes and be able to copy and paste them

How can I remove a previously chosen key? That is, I used to use the 'm' for playback, but now I use the period; however, when I press 'm' to use the camera, the animation plays.

@Radio Guy
Stand Pose tool

What did you use to make ragdolls go into the T pose?

update it pls i want to use it 2025 or add another vid on how to use it in 2025

Oh, the button right next to the spawn model button.

@popcan:
If I understand, you are loading a saved animation; yes.
Using the menu to spawn the model; yes.
Are you then selecting the model then using the menu to load the animation when the model is selected?

if you guys are having issues then you must not be using it right i think because it never failed for me

animator randomly stopped working? Whenever i load an animation it just spawns the ragdoll in the middle of that map and trying to animate just doesnt work.

How can I find it?

guys dont put the command in console just bind it trust me you will have to restart your game

anyone else have problems with the spawn feature? it doesn't work for me at all

sometimes stuck in menu while Im not pressing "+smh_menu" bound key especially right after change framerate and frame count (type numbers with numpad) in my experience.
is there any method to turn off the menu when stuck there? (sorry about my bad english)

playback isn't working, i checked and i have the "+smh_playback" thing binded

Ok, I got it sorted. I just recently upgraded to a new pc and forgot to tick enable world keyframes lol XD, my mistake, thanks for the help regardless

iirc it is case sensitive, so you may want to try "Numpad_1", and check whether you have world keyframes enabled in settings

I seem to be having issues with world keyframes, I've typed the keys (numpad_1 in key to press for example), but it doesn't seem to work, anyone know whats going on?

i used to animate bullshit like a car driving off a cliff with this when i first got gmod,good times

Is there any way to get the physics recorder to record longer than 200 frames? I can manually type in a higher number but it doesn't seem to do much.

I fucking love this mod
