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"

Is there a bug of "glass" material in UE4.12 ?

alt text

The first image is captured in UE4.10.3

The second image is captured in UE4.12.0 and UE4.12.5

I have found the reson is: "glass" material do not support LERP

The question would be appear if i set OPACITY with LERP to link two constants

Otherwise it would be nice if i set OPACITY with one constant only

But it is all OK in UE4.10

Product Version: UE 4.12

Hi Ytianlong,

There are two issues with translucency in 4.12. One of those was resolved and the other is still open, which involves Skylight affecting translucent materials even though it should be blocked by other geometry, like your ceiling in your scene.

That one is still open in 4.12 but has already been resolved in 4.13.
