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"

Transparent Ocean With Displacement Artifacts

Hi there, I have an ocean with waves and it is a translucent material. It is 2 sided. At an angle, you can see through the waves and see it's back face, causing unwanted artifacts. I have tried using this method to cull inner faces:

This unfortunately breaks down since my ocean stretches out the the horizon, and causes noise to appear along the horizon when I adjust the depth bias. Has anyone come across this and know of an easy solution?

You are on the right path, just have a larger bias, and potentially adapt it with distance and/or camera angle, when testing against custom depth.

Ok thanks for your input! I still have the nodes in my material just in case it was the right way to go about it. I'll do some tweaking.
