Unable to set small agent radius in navigation tab

    I'm using the new component based navmeshes / agent type system in 5.6. I have an AI agent (it's a spider used in a VR exposure therapy app) with rather small radius (0.01). However, I am unable to set the radius of this agent to anything below 0.05 in the Navigation->Agents tab. I can, however, set an agent radius of 0.001 under the Navigation->Bake tab.

    Is there a reason why this limitation is in place? It's preventing me from letting my agent traverse the full mesh. I can make some fake geometry that is slightly larger to workaround this limitation, but it seems more like there's something else going on. I submitted a bug report on this issue (issue 899771) that includes a sample project. Just wondering if this is something other people have noticed as well.

    I have the same issue. It is likely a performance limitation to help with collision calculations, but I'd prefer to see Unity give us a warning box rather than just block it. My game isn't that intense, so I can likely get away with it. Also my navmeshes are tiny...

    I am having the same issue as well, for VR development. I'd like an agent radius of 0.01.

    Please unblock the minimum radius and instead show a warning box.
