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"

Can you Increase Specular Scale on Directional Light past 1.0?

i'm trying to increase specular scale past 1.0 on direction lights. UI doesn't let me. Is there an ini setting i can adjust or console cmd?

without it, its imposibble to generate interesting bright specular conditions.

because you can't get any interesting lighting without it.

Also here's what i'm trying to achieve, notice the bright specular on the road? Right now this just can't be done. its just not bright enough.

I'm also dying to have this feature, I'm in shock why it's capped to 1 (I hope there's a technical reason for it, rather than just babysitting artists to avoid non-physically correct values). However my reasons are very different from yours, in your case it sounds like that might be achievable through the roughness values of your materials. If not, you should probably show a visual example of how your failed attempt looks.
