Auto Convex Collision tool crash on OSX

Hi!

How I reproduced crash:
I opened Blender (I use 2.72b) and exported cube in fbx that is there by default.
After that I created a new project (I use TPS BP template) in UE4 (4.6.1).
Then I imported mesh and opened it in mesh editor, then I applied auto convex collision on it with default settings. At this point I get a crash report.

I am using OS X Yosemite 10.10.1.

I don’t know whether I do something unsupported or this is really a bug.

Hi amidabucu,

This is a known bug with Auto Convex Collision on OSX that we have reported in UE-6328. I will keep an eye on that report and let you know when I see an update on it. Thanks for report!

, Is this problem anywhere near to its solution? 4.7p5 still has it.

I understand it may be not high on list but it’s a useful tool for prototyping. Right now I spend a lot of time fiddling in Maya just to see if things work as I though they would. These experiments are taking much more time that they could’ve.

Hi all,

It looks like crash is not in engine, but in a third-party library called HACD which is no longer supported. developers think they have found an alternative library called v-HACD, which they plan to evaluate and switch to if possible. Hopefully this will not be a problem after switch. There is no timeline for this yet, but it is being evaluated currently. Thanks for your patience!

Hi .

I’ve run into this issue, too. Thanks for your updates but it’s been 40 days since your last one. Anything new to report?

Thanks!

Hi Triangle Head,

developers had planned to look into it after GDC, so I don’t have an update for you yet. If we do switch, I would expect to see it in release notes for version we switch in.
