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"

Anyone know why my normal maps look like this in UE4

This is a 4k normal map baked in Blender. It is on a mostly smooth and flat surface in this image and don't know why this pattern of small squares shows up when it should be smooth here.

Could you show us the material node setup and the normal map itself?

Hello masterwigglestein,

Double click on your normal map in your details panel and then check to see if you have it set to normal map under

Compression Settings > Normal Map

Hello Masterwigglestein,

I haven't heard from you yet and I was wondering if you were still experiencing this issue?

Also, if you add a normal map to a surface that has not been UV unwrapped in a modeling software you will experience issues there.

Let me know if you still need help.

Thank you,

I no longer have this issue. I'm not sure if my problem was something I did in Blender or UE4 but I seem to have resolved it somehow. Thank you help though. This can probably be closed.

Not a problem. Thank you for reporting this.
