I'm trying to make arrows fall onto a table, in order to dispose of them on the table randomly. So I enable collision/rigid body on the table, passive mode, and add collision/rigid body on an arrow, active mode. But when I hit alt+a, nothing's happening, and the arrow won't move an inch. I don't remember having to use anything more to get it to work, but surely I'm doing something wrong ? What I am missing please ? Thank you for your help
Scale problem. Since I also used Blender for 3d printing (with scale unit configured at 0.01), all my 3d objects use this scale, and it seems to affect rigid body behavior. I was able to get around the issue switching back to 1 scale unit. It's still not working properly but it's sufficient as for now.
