Probuilder 5 cannot adjust spiral stair inner radius but the older version can

I recently upgraded my Probuilder from 4.5 to 5 and I realized that the new "New Shape" UI is very different from the one in the older versions. For most of time it is more convenient than the older one but sometimes it can be really painful. The biggest problem I found is that I can no longer set the inner radius of spiral stairs. When I create a stair and set its circumference to be like over 180 degrees, its inner radius (the hollow part) seems always to be around half the outer radius. I tried every parameter but no one can make this stair "thinner".


However, in Probuilder 4.5 I can easily create a "thinner" staircase like this. It seems like the parameter "Curvature" works in different ways between Probuilder 4 and 5.


Could anyone help me do the same thing in Probuilder 5?

 

I take it you never got a solution for this?

I just posted the same-ish question myself today: https://forum.unity.com/threads/pro...ent-of-the-overall-object-dimensions.1245631/

Seems like a REALLY big gap between the version 4 & 5 implementations. The current implementation is pretty much unusable for this particular application

 

@sonicm It looks like the value that needs to be manipulated is "inner radius" but looking through the PB5 code, this value is no longer being accepted from the editor. It is no longer a member variable, it seems to be a local/private variable whose value is inferred based on the other dimensions that CAN be set by the user.

Sadly, for 2021.2.* there's no way to load PB4. This really sucks. I logged a bug with Unity but I wouldn't put much faith in this being fixed any time soon.

 

Yeah, it's gone for me too, total deal breaker.
Crazy how Unity just releases replacements for software and tools without it being feature parity to the original first, that's like the bare minimum you could do IMO.

 

It is still broken! Steps angle is wrong!

 

Hello. There is an issue with preview of a stairs shape. CASE IN-39131
