I recently migrated my game from 5.3 to 5.6 and now I’m wanting to use the Niagara System. I’ve briefly used it before and when placing a NS into the world it works fine but when I attempt to open it and edit it the system crashes and gives this report. I’m not sure what to do to fix the issue any help would be appreciated
Considering your log, seems you are encountering a shader conflict. And since you just migrated, it could be related to corrupt or missing data tied to the shader cache, or an engine issue. Please try the following:
First, clear your project’s cache, via closing UE, deleting folders DerivedDataCache, Intermediate, and Saved from your main directory, then re-open UE, and allow it to rebuild/recompile
Next, update your drivers. The best option is to perform a clean install, and choosing “Developer” drivers for the new setup, since those are most stable for engine work.
Finally, check your UE build in the Epic Launcher, check the drop-down menu, anc click “Verify”, which should fix any missing or corrupted components.
If everything fails, please test creating a new Niagara system in your project, and see if the crash also appears there. If this is not the case, then your original system could be corrupted, and need to be rebuilt.
