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 simulate reflexion on movable objects ?

Hi ! I've got this simple scene with spheres with a lot of reflexion floating around in a closed space. Unfortunatly those sphere have a very weird way to reflect their environnment. Is their any way to cheat to make them reflect their environnment ?

Thanks

That's what Reflection Captures are for. Simply place them in your Level and specular/metallic Materials will automatically use the Reflection Spheres to feed the surfaces with an reflection.

However, the Reflection Captures are prebaked, thus you can't "create" Reflections at runtime.

You may also look at this: https://docs.unrealengine.com/latest/INT/Engine/Rendering/LightingAndShadows/ReflectionEnvironment/

You need to use Reflection Captures as I mentioned. They will automatically feed their image on reflective materials

Yes I've understand. There is reflection captures (both spheres and cube) in my scene already. But my movable objects are not receiving any information from them. They receive their reflective informations from the cubemap set in skylight. Is it possible to have a skymap with a reflectioncubemap that affects my movable objects only ?

Thanks
