Raycast Picker issue

[tilak2017]

I am using awayjs lib to render complex 3D models. I have assigned mouse click event for 3d model meshes using Raycaspicker(false).
Raycast Picker is not picking meshes correctly, its not returning the first collision encountered.

If you require the closest collision to be returned, you should be using Raycaspicker(true).

I have checked with Raycastpicker(true) option, its Not working for all conditions. I have attached one obj (shirt.obj). In the attached object pocket and Front-strap meshes are top of the front-left mesh . 1. clicking on pocket is detecting front-left mesh with Raycast picker(true) option. 2. clicking on Front-strap is detecting front-left mesh with Raycast picker(false) option.

Something else you can try is to define a PickingCollider object on the meshes you are trying to detect

by default, picking will only detect against bounding boxes which may be why you're still getting the wrong mesh ie the bounding box of the front-left mesh encloses the bounding box of the front-strap. if you want to do per-triangle picking, you need to set a PickingCollider object on the meshes. You can do this by listening for Mesh objects on ASSET_COMPLETE and adding a new JSPickingCollider object by doing the following:

view.setCollider(mesh, new JSPickingCollider(true));

I realise this system is currently a little unwieldy - if you can't get it to work then you should check out the mouse interaction example source here that implements the same code above:

Hi Rob, Thank you so much for your reply. As per your suggestion, I tried implementing both options but unfortunately both don't seem to work. It works for a few objects but not for the attached shirt object. I am not sure how to solve this issue. Request you to please help once again. The desired behaviour should be: If clicked on pocket/front-strap, it should detect the pocket/front-strap respectively, not the front-left mesh. Thanks & Regards, Prarthana
