(Resolved) [HOU-2887] Houdini crash while interacting in VFB then Houdini UI is unresponsive

[dave.addey]

Hi there,

I'm trying out vray_adv_52002_houdini19.0.455_30f57d7_18421_insta ll_mac.zip on macOS, and I'm experiencing a crash in the VFB. Or, at least, Houdini *reports* a crash, but doesn't actually crash; nonetheless, rendering in the VFB stops, and if I close the VFB window, the entire Houdini UI is unresponsive and I have to force-quit Houdini and relaunch in order to get anything done.

I'm experiencing this with a super-simple scene - literally a cube with a V-Ray Material Builder assigned to it, with a single V-Ray Dome Light. Is this a known issue with the nightly builds? Is there a particular nightly that is known to be good on macOS with Houdini?

I'm using macOS 12.1 on an iMac Pro, with the Python 3 version of Houdini 19.0.455.

Dear dave.addey, hello.

Please download the latest build from today - 18488.
I have just tested it and could approve, but please confirm that it is working fluently on your configuration too.
Waiting for your answer.

Best regards,
TS

Hi there,

I just tried 18488 for Mac with Houdini 19.0.455. The first time I tried it, Houdini crashed as soon as I interacted with the VFB. I've attached a crash log (hindie-2021-12-22-113659.ips.zip)

I relaunched Houdini, opened VFB, and this time it didn't crash; however, when I double-clicked a geometry node to dive inside its network (with the VFB still visible and rendering), Houdini started beachballing, and I had to force-quit the app.

I tried a third time; this time the app didn't crash, but I was unable to cancel the IPR render in the VFB, and the entire Houdini UI was unresponsive. I had to force-quit Houdini (again).

I tried a fourth time; I experienced the beachball / hang again and had to force quit. I've attached a spindump from after the force-quit (HoudiniSpin.txt.zip).

I have also attached the Houdini Indie HIP file that is showing the crash (VRayCrash.hiplc.zip).

As things stand, I can't get anything to work without crashing or spinning

Very sorry to hear that, Dave.
We will investigate further. The issue is logged in our system.

Thank you for the detailed explanation and for the provided files.
In addition, please share - are you using the new Houdini Launcher?

Thank you! I am not using the Houdini Launcher. Fingers crossed it is possible to find a fix.
