alternative to unity's navmesh ?

I've wasted way too much time fighting with unity's navmesh system so I need to find a alternative quickly.

I need to make multiple characters walk from A to B without getting stuck or walking through each other.

I also need to be able to place objects in their path at run time which they will then avoid and walk around.

Even a waypoint system would work for me if it had simple obstacle avoidance built in.

Can anyone recommend a good asset?

Thanks for the reply.

I've used this one a long time ago before it had avoidance, but the new version seems to have a lot of new features since then. I qualify for the upgrade price, so I just bought it.

 

@JBR-games, the link is dead

 

Just clicked on it and worked fine.. Weird. Try it now.

This is a free one i noticed also, but have not tested it to say how it works.
