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"

Texture Transparency


I am using UE4 for my assignment at University. I have created a plant mesh in blender, UV mapped it and have exported it to UE4, everything works fine here.

In my model I used planes with a leaf texture on them, the problem I am having is getting the transparent part of the texture to not render.

Please see attached screenshots.

You need a black/white mask texture either in the alpha channel of the leaf texture or as a seperate texture and use that for opacity mask. Also, for leafs you will want to use the "two sided foliage" shading model.

Hello Job4aCowboy,

Luos is absolutely correct. If you are using a mask make sure that your materials Blend Mode is set to masked. That way you are able to access the Opacity Mask tab of your material. Either you black and white image, set to greyscale, or your alpha channel will be plugged into that input.
