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"

Weird material editor preview behaviour using fresnel.

I have noticed some weird behaviour in general when zooming using the scrollwheel in the material editor preview. I have created a simple material using the default values which only binds a fresnel node to the base color, but the same happens with more advanced ones. Here the material view when just opening the material: alt text

When I now zoom using the scrollwheel on my mouse it will look like this:

alt text

At any moment when i scroll using the right mouse button the material will be fixed and looks like it is supposed to:

alt text

The last image is the only correct one, as the base reflect fraction is set low, so it should be black at normals facing the camera and approach one at grazing angles. This bug also lets the thumbnail preview look wrong, as it looks the same as the in the first image.

Another maybe related bug is when you zoom out far using your scrollwheel, then zoom a little using the right mouse button. Now it is no longer possible to zoom back in using the scrollwheel.

I have tested this in 4.8.1 and also the latest master branch and in the engine itself the material does look correct.
