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 sun height in BP_Sky_Sphere blueprint?

It changes while editing the blueprint itself, but when I override settings in the details tab, nothing will happen, it just stays at 0.469228.

Any ideas of how it wont change? (it is editable in the blueprint btw)

I found the proper answer for this by inspecting the sky sphere bp.

  1. Have directional light set up for the sphere.

  2. Change Y rotation of directional light.

  3. In the sky sphere detail pane, under lighting section, hit refresh material button.

Making the rotation such that the light would look down to the ground means it's noon. 90 degree (looking toward horizon) means sunset/sunrise.

The location of the light actor is ignored. The sky sphere bp only cares about the light actor's Pitch rotation.

You have to remove the station directory light, should be up in the top default section, click to open a new file and njt select clear or none can't quite remember the choice and you will be able to change the sun height

Hey popifrex,

MrAdAbsurdum is correct; find the Light Source actor referred to by BP_Sky_Sphere and change its Mobility from Stationary to Movable. This can be done in the Details panel under Transform, at the very top, when the Light Source is selected. Once that is done, the BP_Sky_Sphere blueprint will be able to adjust its position.

Hope that helps!

i just found out how this works. its just like MrAdAbsurdum said. But you have to rotate the direcctional light, not the sun height. and after rotating it click on the update material in the skysphere details.

Thanks guys.

btw changing the light attached to the bp to movable does not work, it must be removed, or I missed something.

I fixed it by removing the light link to the skysphere, but that might work as well, thx guys!

The information I found in this thread, lead me to find "Affects atmospheric light" in my directional light settings. Now I have full control of the rotation of my directional light, instead of needing to go back and manipulate the BP skysphere. Now I can have more than one sun if I want to. For a different earth kind of effect.

Regards, Rigel
