Hi Fyrestar
Thanks for your reply, morphTargets is exactly what I need, it works like a charm.
But now I have a new challenge , as earlier I was able to cut the wall from BSP with the help of scaling of doors or windows but after morphTargets BSP fail to work and it only works when i change scale factors, but how would I update scaling with morphTargetInfluences or is there any new way I can BSP with morphTarget?
