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 and where to position reflection captures?

I've been recently struggling getting proper reflections in certain places of the map I am working on. The two examples are tunnels and the metal bridge. Bridge is using a metal material with roughness map, sewers are non-metal with spec/roughness maps. You can see my issues in the attached screenshots (ignore poles, they are just there to visualize 3D position of the captures).

I don't really care for reflection details but want to get lighting/specularity right, which seems to partly depend on reflection captures if you have spec/roughness on materials. So with that in mind, my question is, how many reflection captures should I use in a certain space, and how to position them? Should they surround the light source? Be under light source? Between light source and the surfaces? Be far away?

  • about eye height of player.

  • a few with big radius covering whole rooms (one for an entire room) (can be higher up if needed)

  • a few spread out trough room with smaller radius.

  • Around small details the player might walk around a lot.

Its an average guideline ofcourse. thats how I do it at least, and seems to work rather well.
