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 to make depth fog?

So, is there a way to add depth fog in the scene? Not the Exponential Height Fog that goes from bottom of the screen up, but in any direction, alternatively from top to bottom, like a EHF but going down.

I am looking for the effect they have in NaissanceE desert scene when you look straight up be "sky" vanishes in red fog and to the side in yellow fog with a gradient between.

From my previous experimenting I couldn't produce that effect with AtmosphericFog. If you know how to I would be very happy to hear it. Thank you.

Screen shot your settings, and I'll take a look.

I am sorry but there are no settings to share as nothing I am able to produce is even close. Getting the foggy effect on the ground level, the yellowish part in the video isn't a problem. It is the transaction into reddish fog that fades into opaque when you look up that is.

Try ExponentialHeightFog below you will find 2 screenshot of the same scene with and without ExponentialHeightFog. I think you can achieve what you want if you play with the settings.alt text

No, not in a way I have succeeded with anyway. I of course use it to make the lower yellowish fog. But that doesn't help with the higher reddish fog.
