solved [SOLVED] Loaded Dudes do not collide with each other

[AhmedMohamed]

Hello,  need a little help here 
I have a scene where I load a dude and clone many versions of him (about 20). I enable collisions on them,  on a tank in the scene, and also on the ground. collisions work as expected when I order the dudes to moveWithCollision until they hit the wall, and also when they move towards the tank. But : Dudes do not collide with each other, when they come close, they merge and become a single dude. I tried modifying the ellipsoid and ellipsoid offset , made them much more bigger and still the same effect. I tried also creating a bounding box , making it a child of dude , and moving it with collisions instead, but things didn't go so well also.

This is my demo (compressed) - tried to use the playground , loading assets from the github repo url but it didn't work.

I also tried using this function  Temechon provided here to visualize the ellipsoid  , and whatever the size I make of the ellipsoid they finally merge with each other, I see the ellipsoids merge without the slightest objection

Pleasetell me the best practice in this situation, I am sure I am not the first to try to load multiple dudes with collision  

Thanks in advance

Solved . Creating a bounding box and moving it did solve the issue, although I did try it before, anyway thanks
