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 give randomness look to a material

I'm creating a dynamic procedural terrain material based on landscape heights and slopes. This is my terrain material function: alt text

and it look as this:

alt text As you can see, the snow is too much cutted by the HeightBlend function, so i need to add some random noise to make it more realistic.

How i can add some "noise" to the function?

You could use a cloud texture and lerp it through two different versions of the same texture so it gets a more random look. If you set the UVCoord node to i.e. world location or just a random number it would all look more random.

Hey Kheka -

Here is the basic LERP setup using a noise / breakup black and white texture to blend between the texture and a color, but you can do as Luos says and use two different textures as well.
