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"

Material Refracting back on itself?

Hello, I understand similar questions have been asked before, but I cannot seem to find an answer to this issue (If it's an actual issue). alt text The glass material in the image seems to refract back around the corners/through the material when refraction is enabled. It's using the typical setup for refraction (lerp between 1/IOR with a fresnel) so I'm unsure what I am doing incorrectly.

Although I'm using a scene capture cube to fake the reflections, using any of the different lighting modes seem to have the same issue.

Any help would be great.

Thanks, Bob :)

Awesome, exactly what I was looking for! Didn't even know the existence of Pixel Normal Offset refraction.

Thank you :)

In Engine 4.15.2 I have same problem with Pixel Normal Offset enabled! The problem was in this option: alt text

It was enabled first (my project had mobile version) and I got strange squeezed results at the middle and far distance from glass:

Of course it should look (and it does with option disabled) like this:
