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"

Glass Material does not work

For some reason the default glass material from UE4's content browser does not have any reflections, specularity.

I'm on OSX with a GTX650M if that matters.

Isn't it all deferred rendering? This would explain why translucency material isn't not supported well. At least it seems to support cube map reflections. Just saw this in on of the Unreal Engine 4 tutorial videos. I guess I couldn't see it, simply because I haven't much in my scene that could be reflected.

Thanks Samsterdam!

Actually you can mix different rendering pipelines to met different needs. UE4 usese Deferred Rendering for most of the rendering but because transulancey does not work with Deferred Rendering on translucent surfaces, they have to switch the rendering for anything translucent to foward rendering.

How do you do that? At the moment, I never managed to get glass reflections on mac, not even in the content examples

You need a Sphere Reflection Capture Actor (or something like this), it capture the scene around and this is used for the glass material.

Thanks for your reply.

Unfortunately that does not work. I already tried that. It doesn't even show specular highlights.

Umm I do not think glass shows specular because its done via forward rendering so it's not part of the PBR pipeline. But I could be wrong
