Hello, i use a biped (3dsmax) skinned with a mesh like for example a human. I link to the hand of the biped an arm (a pistol). i export the file in b3d format and when import this into my prg i must create a pivot on the hand and link the pistol with entityparent(). After i extract various animation sequence ( 1=stop; 2=walk; 3= jump) from file and i observe that the relation created with entityparent works only in the first sequence but i have need it in all sequence. this is one problem....

Try parenting the pistol directly to the bone . Use the FindChild(mesh,bonename$) to find the bone you want.

OK i will try this. But why this relation aren't exported with b3d file from 3dsmax. I have tried to link in 3ds all mesh with own bone... and don't work fine...
