Hi everyone,

Please see here: [https://playground.babylonjs.com/#Z8HTUN#786](https://playground.babylonjs.com/#Z8HTUN#786)

It seems, when syncing, the physics position takes 1 frame to catch up with the actual mesh position. In consequence the physics raycast misses.

You can fix this by waiting a frame before you shoot the ray. But say you shoot lots of physics raycasts in your code and that code is never async…

~~I tried havok.syncTransform but while it makes the ray hit, it voids the position update.~~ (_guess its syncing the other direction)_

Best wishes  
Joe

Depending on how you wanted to initiate the raycast you could set it up inside registerBeforeRender.

```auto
scene.registerBeforeRender(() => {
        const physicsEngine = scene.getPhysicsEngine();
        var raycastResult = new BABYLON.PhysicsRaycastResult();
        var start = camera.position.clone();
        var end = sphere.position.clone();
        physicsEngine.raycastToRef(start, end, raycastResult); 

        if(raycastResult.hasHit) {
            scene.clearColor = BABYLON.Color3.Green();
        }
        else {
            scene.clearColor = BABYLON.Color3.Red();
        }
])

```
