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"

Widget 3D Transparency

I have added a Minimap for the First Person view which is a Widget3D attached to the camera with little offset, and I would like to add some transparency, similar to what is done in Strike Vector.

I've been trying to add transparency through render opacity, changing the material opacity, changing the alpha of the Textures, but none of these work when I hit play, it renders at opacity 1.

Also, searching through the forums and answerhub I couldn't find any answer to that.

Is it possible to add transparency for a Widget 3D or is it an Engine's limitation? If so, any workaround on that situation?

The widget component has some of its materials parameters exposed. Select the widget component and change the Blend Mode to Transparent:

For even more control, make a copy of the material the widget is using and see what makes it tick.

Thanks for the answer, I've followed your suggestion and also found that there's a BlendMode parameter inside the Widget3D Component.

Setting the two of them to Transparent did the trick!
