Custom Spider NPC moves on its own in a straight line even with NO scripts active. Help!

Hey everyone, I'm facing a really weird physics bug with a custom Spider NPC I imported into Roblox Studio.

As soon as I hit "Play", the spider starts moving on its own in a straight line at a constant speed until it falls off the baseplate.

Here is the catch: **I completely deleted all scripts inside the model, and it STILL moves by itself.**

Here is what I've checked and verified so far:

- `WalkToPoint` is set to 0,0,0 and `WalkToPart` is completely blank/nil.

- There are no hidden physical forces inside the parts (No LinearVelocity, BodyVelocity, VectorForce, etc.).

- The model's `PrimaryPart` is correctly set to the `HumanoidRootPart`.

- `AutoRotate` is enabled on the Humanoid.

- The map floor is properly Anchored.

It seems like a physics glitch or an issue with internal part collisions/rigging pushing the model forward automatically. Has anyone encountered this or knows how to fix it?

Any help or workarounds would be highly appreciated! Thanks in advance.

Blender Animation Model Not Moving in Roblox - Humanoid Compatibility Issue

Hello everyone. I'm developing a horror game called "The Moon" in Roblox and I'm having trouble with an animated spider model exported from Blender.

I created a spider model in Blender with a rigged skeleton and two animations:

  • Walk animation (idle movement)
  • Run animation (chase movement)

When I export this model to Roblox Studio and add a Humanoid component, the animations play correctly on the model, but the model itself doesn't move in the game world.

What I've Tried:

  1. Humanoid:MoveTo() - The spider has a proper Humanoid and HumanoidRootPart, but Humanoid:MoveTo() doesn't make it move
  2. CFrame Movement - I tried moving the HumanoidRootPart using CFrame position changes, but the model stays frozen in place
  3. Different Script Approaches - I've tested multiple movement scripts, but nothing works
  • The Walk and Run animations play perfectly when triggered
  • The AnimationController loads and plays the animation tracks without errors
  • BUT the model's position never changes
