What should I pay attention to when using attachToBone?

Hey @ergou_li ,

I had the same problem some while ago. Here’s the thread:

Ray picking on meshes deformed by skeletons

Hello @flo and welcome! @timetocode is right: Because bones are GPU accelerated you cannot pick them with a CPU operation (meaning the deformed geometry is not in the CPU memory but in the GPU memory). The best way to deal with it is to attach hitboxes to your mesh as you mentioned. This could sound hacky but this is a good viable way to do it Here is a good example: https://www.babylonjs-playground.com/#11BH6Z#395

Here’s the solution were the Pros came up with:

I hope that helps

From my two cents. I think in your code the box1.attachToBone is missing the second parameter. A reference to a mesh. Here’s a link to the documentation
