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"

Hair shader issues

I have simple hair shader and clear scene alt text

If camera directed from the side one (and no lights behind the model) - everything looks good. alt text If any light source is behind the model - I have overexposure. alt text

I have tried different options, tried to use hairs from UE4 sample (and other materials schemes), but current problems is still present. Backlit option doesn't works. Who know how decide this issue?

Product Version: UE 4.14

Hi PGenom,

Back lighting is a bit wonky for the hair shader at the moment. There is a JIRA that reports this here: https://issues.unrealengine.com/issue/UE-39061

You can't see it but there are private comments to the devs mentioning other issues with back lighting. You can keep track of this bug to see if a fix get pushed. It's marked for 4.16 at the moment by may be addressed sooner if we have enough time.

Let me know if that helps,

Hi,

This keeps getting pushed back with every version. It's now "expected" for 4.19.

Can we get a clearer answer on when the fix is really expected?
