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"

It is possible, though from performance standpoint, is extremely impractical.

You would need to calculate parallax occlusion mapping 3 times, and additionally change offset direction based on if the projection is positive or negative. If you are new to shader authoring,it might be better to achieve something more simple at first.

Not to mention that question (probably by OP) was asked on the thread I made about my worldPos function, and I ended up not doing it because the POM mat-function is a clusterf.. of inproper wiring and other stuff.

Yes there is a way, no its not worth my time unless I get paid :p
