Not enough details.

Have you added on both objects a collider? ( with “is trigger” unchecked )

Hi,

![708599--25575--$Capture.PNG](https://europe1.discourse-cdn.com/unity/original/4X/a/0/4/a040a922960b10a97164b836784dcfe84120d02e.png)

I finaly found a solution.  
This option has solved my problem, probably it’s because my models are too small 😛 eheh.  
I will learn.

i just turn the value to 0, and all is ok for now.

Thanks
