Collision bug

[josemendez]

it's doesnt do much
updated code

Code:

public void Spawn(JellyObject prefab, Vector3 position, Quaternion rotation, Action<JellyObject> OnSpawn = null)
    {
        instances++;
        int id = instances;

        JellyObject jelly = Instantiate(prefab, position, rotation);
        jelly.transform.SetParent(jellyParent);

        spawnedObjects.Add(jelly);
        SetRandomColor(jelly);

        jelly.spawnID = id;

        OnSpawn?.Invoke(jelly);
    }

As per my first post: have you checked the collision filters, in case they’re set to not collide with each other?

These are set on a per-particle basis on the blueprint. I assume you’ve created the blueprint in-editor, then assigned it to the prefab instantiated by this code?
