FIVEFORGE / Guides / FiveM Prop Has No Collision — How to Fix It

FiveM prop has no collision — the fix

You spawn your custom prop and walk straight through it. There are only three realistic causes, and they are all in the metadata rather than the mesh. Work through them in this order.

Cause 1: empty physicsDictionary in the ytyp Cause 2: no ytyp at all Cause 3: collision was never exported Also check your spawn code FAQ

Cause 1: empty physicsDictionary in the ytyp

This is the one that catches almost everyone. Your .ydr can contain a perfectly good embedded collision bound, but if the archetype in the .ytyp has <physicsDictionary/> empty, the engine loads the visual model and never mounts the collision.

The field has to name the model itself, and the archetype flags need the physics bit set:

<physicsDictionary>my_prop</physicsDictionary> and flags value="32"

Symptom check: the prop is visible, correctly textured, and completely non-solid. That combination is this bug, not a mesh problem.

Cause 2: no ytyp at all

If there is no archetype the model never registers, so you do not get a collision bug — you get "model failed to load" or an invisible prop, because RequestModel never resolves. The manifest also has to request the archetype file:

data_file 'DLC_ITYP_REQUEST' 'stream/my_prop.ytyp'

Cause 3: collision was never exported

If you built the prop by hand in Blender with Sollumz, embedded collision is opt-in — and when it does get created it inherits the visual material, which produces a "non-collision materials" warning and a bound the game ignores. The collision mesh needs a proper collision material assigned, not the visual one.

Also check your spawn code

A prop with valid collision can still behave oddly if it is spawned as a non-frozen object. For static world props:

SetEntityCollision(obj, true, true) then FreezeEntityPosition(obj, true), and guard with IsModelInCdimage before requesting.

Props exported from FIVEFORGE ship the archetype, the physics dictionary reference, the flags and a working spawn command already wired up.

FAQ

Why can I walk through my custom FiveM prop?

In almost every case the .ytyp archetype has an empty <physicsDictionary/>. It has to name the model, and the archetype flags must include the physics bit (32), or the engine loads the visuals and ignores the collision.

What does "model failed to load" mean?

The archetype was never registered — usually a missing .ytyp, or a manifest without the DLC_ITYP_REQUEST data_file line. RequestModel then never resolves.

Should I use box or mesh collision?

Box collision is cheaper and right for crates, signs and boxy props. Mesh collision is accurate and worth it for props players climb on or drive into. Use none only for pure decoration.

Do FIVEFORGE props come with collision?

Yes. You pick box, mesh or none in the editor, and the archetype, physics dictionary reference and flags are written automatically.
