Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Editor crashes on applying Material to BSP

This problem has only started happening recently, and only on a certain level. The editor will crash to desktop any time i try to apply a material to a BSP brush. This problem only occurs when using the Default/starter content materials. Any of my own have no issues. There is no crash when applying the material to a static mesh though. I couldn't find anything in the event viewer, and the error log Unreal gives me is 80's technomancy to me:

Other logs show everything normal. Another thing: This error only arises on a single map. Loading up the "Firstperson example" map in the same project and placing a BSP brush and applying a Starter Pack material to it (M_Metal_Rust) will not crash it, but doing the same on the other level will. The level in question has 17 BSP brushes, 73 or so Static meshes, and a 7x7 Landscape. 2 directional lights as well as a sky light. There is a postprocess volume for autoexposure in a certain area, as well as roughly 4 particle systems, 3 of which have been scaled up . Any brushes that had the starter content material applied to it (typically M_Metal_Rust) do not cause errors and will keep their materials. Opening up the offending materials in the material editor works fine.

I've been googling this problem for a few days now, doing things like deleting my "Saved" and "Intermediate" Folders but to no effect. I've also checked my project (Blueprint based) for null pointers, but still nothing there (although i'm not sure i've gone over everything). I believe the error arose after i reorganised my assets into different folders. But that shouldn't effect the starter content materials.

To recap: Applying starter content material to a BSP brush will crash the editor, but only on 1 level.

I'm stumped, so hopefully you guys can help me.

Hi BillyBobCornCob,

  • Does thi soccur in a clean, blank project with no additional content or is it limited to this project?

  • What steps can I take to reproduce this on my end?

  • Can you post your dxdiag here so I can take a look?

  • Can you post your crash logs so I can view these as well? They can be found at \Unreal Projects\PROJECTNAME\saved\logs\

  • What specific materials are you trying to use?

  • Is it on any bsp brush or a specific brush? Has this brush been modified?

This is limited only to this project, and only this level. I'm not sure how you can go about reproducing it, but in theory you would place a new Cube BSP brush, and try and apply any "starter content" materials Also try using subtractive brushes as well. Material must be placed last. M_Metal_Rust seems to be the biggest offender, but it crashes with any of the starter content mats. Here is DxDiag: http://pastebin.com/raw/PZ3rJ5KZ [1]: http://pastebin.com/raw/PZ3rJ5KZ and Log: http://pastebin.com/raw/yzkuNWki

Unfortunately I have not been able to reproduce this on my end as of yet. Do you have a sample project you would be willing to share? I'll be happy to take a look and see if I can recreate this on my end.
