My raycaster can’t seem to find all objects, mostly related to when an animation is added, when I remove the animation it seems ok I am using this code to find objects raycaster.setFromCamera(mouse, camera); ObjectToTest = []; scene.traverse(function (child) { if (child.…

I don’t know what might be happening for you, but for what it’s worth, we’re also finding the ray caster can fail to return expected intersections in some circumstances. I haven’t dug into why, but it could easily be explained be the presence of skinned mesh, if that throws it off. TL;DR :eyes:

Hmmm, that is not really good news, how do you work around it?

You may need to set a correct .boundingBox on the skinnedmesh: [image] Get Location On Click of skinned mesh object Questions SkinnedMesh does support raycasting since transformed bones are taking into account. I thought this was addressed recently in PR #19178 by accou…

I managed to get something to work with scene.traverse(function (child) { if (child.isSkinnedMesh && child.boundingBox !== undefined) { child.computeBoundingBox(); } }); I applying this when loading the animation. I thought it wo…

Animated mesh bounding boxes change as the animation progresses, so computing the bounding box of a skinnedmesh with no animation applied will get the bounds of the bind pose which is often tiny/giant/wrong. You might want to just make an educated guess and then just set it directly as a test like… …

[image] manthrax: child.boundingBox = new THREE.Box(); let sz = 100; //Adjust this until it works try like 1, 10, 100, 1000, etc child.boundingBox.min.set(-sz ,-sz ,-sz ); child.boundingBox.max.set( sz , sz , sz ); as a guess… That was a good idea. I put some BoxHelper on them and now I see …

[image] manthrax: Otherwise… you could try playing your idle animation or whatever and then compute the boundingbox on the first frame, but that’s a bit fiddly. I have this boundingbox code directly after assigning the animation. Is it possible to apply here the first frame glbac…
