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"

Perlin Noise Material Editor

I tried using perlin noise to generate heightmap by combining a couple of functions on a different octaves as explained on http://freespace.virgin.net/hugo.elias/models/m_perlin.htm

Hey ernesernesto -

You will need to Clamp the output of the Noise to 0 to 1 (though you could also set the minimum Output to 0 as well). You will probably also need to add some smoothing through the Filterwidth and adjust your scale to way way below 1 (like 0.0575 gave me a good result). The Levels in the noise node refers to the levels of noise that the module is mixing to generate a noise field.

Here is what my material ended up looking like:
