When I try to compile after adding a SetMaterial node to Blueprint, the editor crashes.

Here is a video showing the problem.

HI ,

Unfortunately, I have not been able to reproduce this on my end.

  • Does this occur in a clean, blank project with no additional content or is it limited to one project?
  • What steps can I take to reproduce this on my end?
  • Does this only occur with a specific asset or is it any asset?
  • Can you post your crash logs here? They can be found at \Unreal Projects\PROJECTNAME\saved\logs.
  • Can you post your callstack after the editor crashes?
  • Can you post your dxdiag here so I can take a look?

Well, now I find that DXDiag is having trouble accessing DirectShow.

Guess i’ll have to format.

Please let me know if reformatting fixes the error you are seeing. I will leave this post open for a few days.

After formatting, DirectShow is no longer crashing DXDiag and so far, attempts to reproduce the compile crash have failed. though I foolishly didn’t save the project in it’s broken state, so I can’t be sure it wasn’t something else I did afterwards while finding a workaround, but I’d say it’s safe to assume it was something weird on my end.

If it happens again, I’ll post another report. Sorry for the wild goose chase.

I’m happy to hear this is no longer occurring for you. I am marking this as answered for tracking purposes. If the error occurs again, please post back here and I’ll be happy to take another look.

I discovered the DirectShow problem was caused by a “Vorbis.acm” file that some other programs like FL add to System32.

The presence of this file also makes Sony crash when it scans for Plugins on startup. The solution is to temporarily move the file out of System32.

Now that I know that it’s an Audio codec, it would seem unlikely that it was the cause of my particular problem. but as I said, if it happens again I’ll be back! with at least the logs and an affected project. but hopefully, giving my PC a fresh clean will be enough. :slight_smile:

Thank you for your attention.
