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 can I create a sandy wind effect?

I'm making a desert/wasteland-like environment and I would love to add a reoccurring wind to blow sand across the landscape and even have tumbleweeds rolling around. any suggestions or resources that can describe nice a workflow?

Hey L.f.Gutierrez,

There are tons of resources out there for the effect you are going for, and even templates to base your particle systems. I highly suggest taking a look at the Particle Effects project and the Elemental Demo provided by us on the Learn tab of the launcher for ideas on how to create the sand blowing across surfaces.

In the Particle Effects demo project they use things called vector fields to control how a number of particles passes through an area in which you can define their behavior. This is just one way to add a sort of dust particle effect. For the windy sand, you would more than likely use a set of SubUV animations of dust clouds shifting over time. You could use the SubUV within your particles systems and add more particle emitters and modules to tweak the effect to your liking.

With the two projects I mentioned and some reverse engineering, you should be able to extract some good ideas and templates on how to create the effect you are trying to achieve.

Cheers,

Andrew Hurley
