Greetings @mymotherhatesme7

Does this happen on one specific project or every project? Also, what your system specs/UE version/etc? I’ll be happy to take a look! Thanks!

Hey thanks so much for replying. It happens in every single project that includes my hda file! I import my hda file, it then freezes/buffers for a few seconds when I put it in my actual 3d scene. Then when I select a cube to be the hda’s input subject it crashes without fail every time.

My system specs:
-windows 10
-32gb ram
-gpu: gtx 1080 ;8b memory
-cpu i7 6700k ;4 cores
-500gb ssd/13tb hdd

I read that my Houdini version “19.5.435” works with Unreal Engine “5.0.3” so I use this version.

Also the hda file is just a building generator. You create a cube in unreal and it then turns it into a building with windows, etc. I’ve followed a tutorial and it works correctly inside houdini, the only problem are the crashes in unreal.

Thank you

Sorry here’s the error log I don’t know why it was deleted. MyProject

This may be a bit of a shot in the dark. But, is this the same type of scenario you’re running into? Unreal Crashes when using input Geometry as an HDA (Houdini digital asset) input

Sadly, I am using a production build of houdini 19.5.435! The error persists.

Hi! Were you able to get the houdini error resolved?
