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"

Failed to find shader map for default material WorldGridMaterial!

Hello everyone! I´ve posted this question on an existing thread in "Bug Reports" since the user was having exactly the same problem. But i dont think this is a bug but something i am missing. Anyways nobody could help this guy so i am posting again in the correct section...

I am trying to pack a simple architectural interior level. Everything runs ok while on the editor, no errors when building and no errors when packing the game. The problem comes out when we try to run the .exe file. I´ve attached a screen capture showing the error. I think we´ve tried almost everything, we´ve also merged all meshes, textures and materials into a new blank project with no success.

Hope someone could help us solve this. Let me know if theres any other relevant info i can give you so you can give me a clue of what´s happening.

Thank you all!!

Edit 2: I managed to fix this by creating a new project and adding content from the old project to it. Packaged it and it's working fine now.

Hi Syneh. I think we found a solution for our problem...at least we could run our packages without any issues. The problem was solved since we restore default values on "Lighting" settings, under "Project Settings" >>> "Rendering". We were turning off static lighting since our illumination was completely burned in 3dsMax, so we didnt need any Unreal Lights in our scene...

I´m attaching an image showing the parameters that we have to left by default. Let me know if this solves your problem too so i can report it as a Bug.

Im glad to hear that. It would be great if someone from the staff could tell me if this thread is enough to let them know about this issue or if i should create another thread under "Bug Report".

(Sorry about my english...if something of what im writing is not clear just let me know so i can explain myself with other words)

Howdy JakeChoe,

Thanks for the information about the issue that you have been experiencing. We has had other users experience issue with the WorldGridMaterial and have written Jira Report UE-12213 to track this issue.

A fix for the issue has been checked in yesterday (not verified yet) but should be placed into an upcoming release of UE4. I am unsure as to when or what version this fix will be implemented but I will be sure to keep you posted as I know more.

It's almost a year later and I'm seeing the same bug (using ADB Logcat) in UE4 4.10. It seems to be the reason my Android build is failing.

UE-12213 was fixed in 4.7. If you feel that this issue is still occurring, it would be best advised if you created a new AnswerHub post with full details and any additional files/logs that would be necessary for investigation.
