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"

Texture - Statistics Viewer


I wanted to learn a little more about optimization in UE4 concerning textures. So I just did a simple test in the UE4 engine where I only have 1 chair and nothing else in the level/map.

The main mesh of that chair is using a material with a 1024x1024 normal map. (named T_Chair_N)

I put an instance of that chair in the level and I change its material with a placeholder material that has a 512x512 normal map. (Named T_Placeholder_N)

I save and then Open the Statistic Viewer from the menu Edit.

I go to the Textures Stats section with the Selected Actors option. Then I see that both normal maps are loaded. T_Placeholder_N and T_Chair_N.

Does this mean that no matter what material we apply on an instance, it will always load the material of the parent mesh or is there a way to not load the material of the main mesh?

Is this issue already corrected in a newer version?

Thank you in advance for your help!

Product Version: UE 4.11
