solved computeBonesUsingShaders = false , animation can not apply to individual mesh

[foxcoder]

hi , 

if i load one mesh , and make multiply copies for the mesh and skeleton , 

if mesh.computeBonesUsingShaders  = false , and create animation scene.beginAnimation for cloned skeleton with different setting , 

the mesh animate all the same , below is the example i created in playgound 

https://playground.babylonjs.com/indexStable.html#QY1WYT#12

it can be fixed by set mesh.computeBonesUsingShaders  = true , but i need to get updated boundingbox in the end of the animation , 

using shaders won't update the boundingbox even use refreshBoundingInfo , 

so another question , is it possible to get new bounding box at the end of animation using computeBonesUsingShaders = true ?

Thank you in advance

Best Regards

hi ,

just to reply my self , through start reading the source code , i found the issue,

for software skin , babylon will do mesh.applySkeleton on every frame , the trouble is clone the meth , will not get a new copy of Geometry , and copy function don't provide copy geometry parameter,

i manually copy geometry after clone , solve the issue , code below do the trick :

let geometry = rabbit2.geometry.copy(BABYLON.Geometry.RandomId());
geometry.applyToMesh(rabbit2);

geometry = rabbit3.geometry.copy(BABYLON.Geometry.RandomId());
geometry.applyToMesh(rabbit3);

below is an updated playground ,

so is it a proper workaround ? will it have any side affect other than performance ? 

Best Regards

yup, this is an expected behavior and instead of cloning the geometry you could call makeGeometryUnique on the mesh:
