Help Need make dificult configuration

[alex798]

Hello,

I encountered such challenge- need to make chain pass through torus(mesh collider) when it is pulled from the other side(Look in attachment), but as soon as scene starts it passes through said torus...
The question is where to configure particles mass(to make it lighter so that it won't fall with such speed), or if U have other suggestions(i did it with cursor, but it requires additional particles and don't look realistic)...

Hi!

The question is where to configure particles mass(to make it lighter so that it won't fall with such speed)

Mass doesn't affect how fast objects fall (not in the real world, not it any physics engine). In absence of atmospheric drag to slow down falling objects, all objects fall at *exactly* the same speed regardless of their mass. This is physics 101, watch this video for a demonstration:

So adjusting mass won't help. In case you do need to adjust mass for other purposes, you can do so in the path editor just like any other path property (thickness, color, etc):

or if U have other suggestions(i did it with cursor, but it requires additional particles and don't look realistic)...

Try to use a distance field for the torus collider. Will be both cheaper and much more robust than a mesh collider. Also, try making your torus thicker. Such a thin object is bound to cause tunneling issues.
