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"

How to rotate HDRI background with reflections and improve the image quality

I want to rotate a background hdr image and have the reflection updated property. currently i have to rotate the whole scene(expect the background) to update hdri reflections. if i just rotate the background the reflection stay the same...

see imagealt text

and i want to unlock the hdri resolution 512x512 is a bit to blurry, how can i do this? as you can see the background is really blurry i would like to have a sharp image, do i have to create a seperrate image(no hdri) as background and use the real hdri ligting in the postprocess volume(cube map)?

Just use a hdr image in an skylight, rotate the image in the material with parameters and recapture you the skylight component every time you up date the hdr image rotation.

can you follow?

Hi -

I corrected DarknesZ's link to a Public facing version of the answer. Let me know if you can still not access it.

Thank You
