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"

How can I change the size of the Sun?

Hi Guys,

I am very new to all of this and was messing around with the basic Skysphere setup in a Blank (4.2) Project. I've come to notice that the visual appearance of the Sun is based on the properties of the Directional Light that the Skysphere makes use of?

Is this correct? If not my apologies.

I believe I understand the purpose behind this setup but I am unsure as to how one would make the Lightsource (aka, the Sun) appear bigger in the Skysphere. I tried changing the scale of the Directional Light among other things but did not see a result. Any help to point me in the right direction would be appreciated. Sorry for being a newb.

Hi NoDroneDigital,

Here are the steps for how to change that:

  • In the Scene Outliner right click on BP_Sky_Sphere and select Edit BP_Sky_Sphere.

  • Under the Construction Script find the Create Dynamic Material Instance node.

  • Find Source Material under that node and click the arrow to the right to find the material in your Content Browswer.

  • Double click the material to open it in the Material Editor.

  • Find the section named Sun and change the Default Value of the SunRadius node.

Hope that helps, TJ
