Really Struggling with animating models

I’m am so confused… I’ve been trying to animate this one model for a very long time and I’m at a point where i don’t know what to do so I’ve come here

I’m trying to animate a carriage

I need the HRP to be animatable but whenever I put it in the roblox animation system it only lets me move the unions. (the unions wont even move they snap back to the same place as before)

I know the unions can’t move due to the weld in the HRP but I don’t even know what to do. I have a few scripts inside that play a tween on the wheel but I genuinely don’t know what to do.

All I want is a simple HRP that I can move and animate that the entire carriage will move with but will still allow the wheels to tween.

Thanks (I might be cooked)

Animator will not work with Welds as part of the animated Model.

So, try having a model within a model, like so:

For this one, the Animate model is animated. The Welds model has all of the parts that player actually sees.

Here is the file, you may have to re-publish the animation to see it:

Wheels.rbxl (137.0 KB)

Thanks for helping me out, but I’m a bit confused on what goes where based off this image.

I don’t think the humanoidrootpart is animatable, so maybe you’ll have to make a different part with all of the welds, and then weld that part on the hrp. (When I mean weld, I mean with the motor6Ds.)

You can download the file instead of looking at the image.

Animate = Model with invisible parts that are animated with a [ROOT].
Welds = Model with visible parts that are welded to the parts inside the Animate model.

Wheels = a model that combines Animate and Welds models into one model.

Use Motor6Ds instead of welds, Motor6Ds are basically welds but they have the Transform property which makes them animatable.

I have done this but for some reason it will not let me move the hrp at all or even add it to the animation. Whenever I use one of the unions as a makeshift for the hrp it lets me add it to the animation but I try and move it and it slides right back to where it was.

I have this so far…

not 100% sure if im on the right track but whenever I put this in the little roblox animator It doesn’t add the hrp or the base.

when it does add something though it doesn’t let me move it at all

Make sure the model you are animating has a PrimaryPart assigned in the Properties window.

Make it the PrimaryPart the HumanoidRootPart since you have one.

I did that

It still doesn’t add the hrp to the animation at all for some reason and I can’t move any other of the unions in the model.

If you just want the wheels to spin then use a Hinge with an Motor as the ActuatorType:

Here is a video that explains how to do that:

No, I already have a tween that’s supposed to play for the wheels I’m just trying to also animate the carriage at the same time.

Maybe make the base the primary part, basically maybe try to make the base the hrp, but idk if that ruins any of your scripts.

I have already but its still not seeming to work.
