I think there's a problem because the AI creatures don't move much at all. They just slowly drift around and don't eat any food.

oh

seems to work on my side though

try checking sim frequency and make sure it at at least 200 hz

the bugs are also blind so they feel their way around

so if their antennas feel food, they will move their mouth towards it

also make sure air friction multiplier at 45

Those parameters that you mentioned will be set to the values that YOU gave them when you saved the scene. So, they are all correct but the bugs hardly move at all. They just sit mainly in one spot and barely move at all. Are there any control keys that need to be pressed in order for them to move?

this glitch is strange

you can try chescking the thruster in the back of the bug and make it faster.

*checking*

your computer might be differentand you can do things like decrease air friction

and you dont need keys to move

Okay, it works now after I turned off air friction. You must have left air friction turned on when you saved the scene because it was on when I downloaded it. Air friction and gravity will be on or off depending on what state they were in when a scene is saved. So, you might want to edit the scene and save it again but with air friction turned off.

air friction was used to prevent it from drifing out of control. the physics on my mac might be a little different

Yeah, I think you're right. Sometimes differences in computers and operating systems can cause scenes to behave differently. Unfortunately, there's not much that can be done about that.
