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"

Specular reflections visible through walls

I was working on a prototype map and noticed recently that specular reflections (from stationary point lights) were showing through walls. Is this a limitation of the engine? If so are there any good workflow/workarounds I could use to minimize the issue?

The red light is from the small room.

Hi ook,

This is a limitation of using reflection captures.

This page will cover the basics and this is mentioned in the limitations section at the bottom of the page: https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/ReflectionEnvironment/index.html

This second page that should also help with basic uses and how to properly use reflections captures as well: https://docs.unrealengine.com/latest/INT/Resources/Showcases/Reflections/index.html

I hope this helps.

Ah makes sense. So I'm seeing the information from the reflection capture inside the room. I'll try a cubic capture as well and see if that helps my case. Seems like thin walls are just a pain. ;)
