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 create ocean shoreline ?

Hi ,

I was able to create ocean material using Grestner function , as you can see in the below picture.

![alt text][2] But I want to create realistic shoreline and the wave turbulance when the ocean interacts with the beach. Kindly let me know how to achieve something like that. I was unable to find a proper tutorial.

I think depth only works with translucent materials. He seems to be using an opaque one.

Then I guess you'll have to manually paint your shoreline.

No , I changed that to translucent. But it works nicely , I just have to figure it out what textures and modifications to be added instead of a constant param of red color , but the result is really amazing for now , and just what I wanted. Thanks a lot. Will try to implement further by referring to this pdf file -

Unfortunately, there's a huge disadvantage in using translucent for water shading atm — reflections. It works fine for small water planes but it's horrible for big planes. I hope Epic will fix it soon.

Agreed TimGS, definitely need reflections AND translucency. Really hard to make water look convincing without both.
