Sorry for late reply .I am using the M113 blueprint tank.So I was going through one of the post where you mentioned that you can’t get too many tanks in scene because of performance drop.I also looked for some optimization techniques mentioned in that post which were great. But In my case I am planning for 50+ tanks in single scene. If I cant get realistic tank movement because of performance issue I would be happy to explore other options like hover tanks(which I think is great).Will they will be more efficient in terms of performance for example hovercraft movement calculation wold be faster than tank movement?
This is one of my old time favorite game where the robot and tank hovers.Mind the volume
