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 do you change Landscape Material with volumes?

So I am making a landscape material which textures based on slope angles but one thing I want to do is be able to set up biomes quickly and my idea is to use triggers / volumes that change the material.

So if the landscape has no volume it is normal grassland, if the landscape has a bubble / volume on it called forest it changes the textures in the material to forest textures, if the volume is called swamp it changes the materials to swampy textures etc etc.

I hope I am explaining this correctly.

You can use Material Parameter Collection and several sphere mask or box mask material expressions for that.
