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"

Hi there, Does anyone know why is my imported HDRI so badly pixellated? alt text I'm using a 4k HDR imported from Hdri Haven and have been following this tutorial: http://rag3dviz.com/tutorial/hdri-lighting-in-unreal-engine/2/

My material Bp: alt text alt text

What am I doing wrong?

I've tried changing skysphere scale from 1 to 3 makes no difference, no mipmaps is also set within the material

Hi, sorry to necro this old question - expose the advanced drop down arrow under the compression header, and change "Set Maximum Texture Size" to 2048.

UE4 clamps the hell out of HDRI's by default for some reason, hopefully this helps.

It's not for some random reason. Up until today, HDRI images were used mainly for baking light and reflectiosn in videogames. That's the reason of compression quality and aggressivness, since HDRs are usually heavy images. Straight up config from UE is not for thought for high end image rendering as ArchViz requires. UE4 is a Game Engine after all. But it's a great one and allows it to be used for cinematics also with just a few tweaks around.

If you don't want your texture to compress make sure you select the option in the texture edit tab and also change it to never stream.
