Pro Builder - StackOverflowException with Boolean Tool

Some of us are having those errors when Applying Boolean with the experimental tool. Is this bug logged please?

I'm seeing this too. If you haven't already, please log a bug for it.

 

You know...it's funny ProBuilder was BUILT around CSG. Which is Boolean Operations, and yet they were always "might work, might not"..and now just a "Nope"
No offense, but this is just aggravating as all @#$%^&
Just about every other True CSG (not using shader tricks that don't actually change the mesh) all have flaws in Unity. Why is this??

 

Hey,

I was having a similar issue where I was trying to cut a cylinder into another cylinder. Figured out the issue was too much geometry (I imagine too much vertices makes calculating subtraction a bit too much). I figured out how to remedy this by making the object I was subtracting from my main object have fewer sides to it. Hope this helps!

There has got to be a better way to perform a boolean operation on the mesh. Probuilder just isn't doing the job.

 

This is happening for me too. It worked in previous versions. I'm in a HDRP project, if that makes a difference.

 

same here. boolean operations reliably crash unity now.

 

Having this issue too.

 

Yeeppppp.... 2019.4.9f1 -- Regular 3D project, Probuilder CSG ops is borked with a stack overflow.

 

It also happens to me right now. I need a csg api to get intersect some meshes . Any idea ???

 

I don't actually know how but I got it working. I tried creating a new script and forgot to check what script it was in but i can't find it.

 

Change the sizing of the intended shape that you are cutting, it worked for me after a restart of the editor. I hope this helps.

 

when you press substruction make sure that u see the new game object wish is the boolean that you are looking for ..

 

Probuilder is just buggy as all heck even beyond the issue that boolean operations crash unity/don't work. Is probuilder going to be supported going forward or is something else going to be responsible for boolean operations. Thanks!

 

Hey there, is this bug fix merged with 2021.2 branches, if not, do you know when it will be? thanks!

 

Fixed!!!! FYI, I'm on 2021.2.13f. I would get 100% repro of the unity crashing on boolean: subtraction operation and it is working really good once i moved to 2021.2.13f. Thanks!

 

Im still getting this, and its a year on, is there likely a fix for the boolean tool soon?

 

i tried the 5.0.7 package provided through package manager, and the 5.1.0rc off github.

 

Submitted, but its late and i got to work early so sleep time now

 

@kaarrrllll out of interest, having submitted the bug, i dont see it on the issue tracker a month later..

 

i dont know.. I submitted as I said over a month ago and have heard absolutely nothing

 

@kaarrrllll so, I found it.. after some help from someone else, it seems your jira system doesnt email me - even though when i couldnt remember my password it happily could send me that - it seems it got closed because I didnt respond to the thing i didnt know where it was, or that someone had asked me a question.. After all, I couldnt find anything that took me to the jira system, or that it in fact went to a jira system. When i did get a link it said i had no access.. so.. yeah.. not exactly helpful.

So I have poked it open it is IN-44084.. currently.... although they reproduced it they closed it... this is the kind of thing that gives people bad names. I will try and keep an eye on it, but as its not easy to get at.. It seems unfortunate

 

as I said I poked it having found it, still not getting any emails though

 

@kaarrrllll good news! Unity Issue Tracker - Silent crash when Subtracting two objects via the Probuilder&#39;s Boolean Tool (unity3d.com)
