Hi ! Great Babyloners ;
I was searched and tried many methodes for multiple character cloning with multiple different animations for in same scene and created simple way.
( I m not good for babylon if a mistake in my way pls be warn. )
Simple low poly Multiple Character clone with , Multiple Animations from 3dprof.com
low poly Male and Female character with 4 clones , 4 different animations same time.
( characters can expor from 3dsmax , blender etc. to .baylon file )
-not need animation groups,
-not need animation range,
-just sequential animations by keyframe.
Mesh files must be .babylon format, cause .glb file format and webgl2 cant clone skeletons yet ???
