3D Model problem - Cinema 4D

What are you trying to do, its not very clear?

If I understand correctly you want it to recognize your robot and not intersect? GLTF models don't have a collision cage so they don't know there is another model in the same location.

Okay, I'll try to explain better. I'm working on something like small low poly city, so in the streets I've cars which are static, they're don't moving at all, so only thing which is moving is my robot/character, so I've solved problem with buildings I can't pass through buildings, but through car I can, on some car I can pass just when I try from left side of car, on other I can from all sides, on other car I can just from front side, so all cars are the same model but they aren't behave in the same way. Thanks!

lol... Again, not enough information.

You have solved the problem with your buildings... I assume this is the same problem, how did you solve it?

Can you upload a video of a screen capture of what you are doing? Without seeing what you are doing its very difficult to interpret what you are talking about.
