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"

What's the best possible sky box I can create?

There was a highly upvoted topic in the unrealdev subreddit a few days ago where someone asked for a proper tutorial to create a good looking skybox. There is one tutorial out there from Fragged but it produces a rather bad looking skybox.

Can someone who knows his way around sky boxes please outline what tools to use and how to create a really good looking skybox?

I have attached the best I was able to come up with so far and its still not really sharp, bending in weird places and so on. I use a 4096 x 4096 tga texture on a big sphere.

Ofcorse just sticking texture on choppy mesh won't look nice, you need to design good material (which is kind of like a shader blueprint) for it which will make skybox good, you got all this math logic there to do all visual trickery. You could compose multiple textures there, mix them to look nicer, you could alter UV map to surface the texture more optimally as currently shape strachges it. Remember that pixel shaders always output 2D image , just disturbes textures based on UV maps which makes it look like 3D, to understand what i mean make a material which use texture but uses normalized screen position as UV map, it will open your eyes and might inspire you.

I gonna give you my tip i always say in terms of visuals, be illusionist,think out of the box, you are director of spectacle and it does not matter what you see and what you design even if it feels strange to you, what is impotent it's final result and what player see.

He shows a little of how he did that in his video, and itr seams he made actor which compose multiple components for this effect: https://www.youtube.com/watch?v=ZxrcwNGnXZc#t=2325
