I’m trying to learn UE5.2’s Deformer Graph system, but getting tripped up right out of the gate. I’m following Epic Game’s tutorial for setting up a basic deformer graph, but when I go to compile, the project just crashes every time, with this error message:
Assertion failed: Pair != nullptr [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Map.h] [Line: 643]
Any ideas what might be causing this? Is anyone else having better luck with the Deformer Graph?
Yes,same as i faced.After i click the Compile button ,the Editor Crashed!Did you submit thebug report to Epic?
I did not. I’ve been assuming this is not a bug, and just something I need to change in my settings. Surely they wouldn’t release a plugin that can’t even make it through their own tutorial procedures without crashing…
…okay, maybe I should submit a bug report…
I’m having constant crashes when trying to compile my blueprint that contains a skeletal mesh with a deformer. Have you found any solutions for this?
Not sure if this helps, but I’ve revisited the Deformer Graph since my initial failures to get it working, and it seems that part of the problem may be due to a bug, but also part of it is because that tutorial gives terrible instructions. It instructs you to compile the graph as soon as you’ve set up the inputs and outputs for your custom kernel, before you’ve connected it to anything. This seems to always trigger a crash. However, if I ignore that step, and continue with the rest of the setup, then only compile once everything is fully coded and connected, it actually does compile and works exactly as advertised.
Also, I’ve noticed that they have given the Deformer Graph a bit of an update in newer versions, so there are some minor tweaks necessary to get things set up now. That may have nothing to do with your problem, but that it is how I was able to get it working, for my extremely basic use case!
