Hi, my name is Jan and I help companies by creating short videos for their websites and internal use, mostly as a freelancer for agencies. I post daily one-minute tutorials for Blender users and wrote the popular "Blender Secrets" e-books.


      • Hi again,

        Don't misunderstand Me here, please. The result is not realistic, it maybe can work, for some type of stylized effect, etc. I was on the same effect recently, but for a grass, bunch of grass. Sadly in Blender even if You will try, there aren't tools to do it. But finally, I make it with animation nodes. For a single object, much better is to use curve deform, and curve with soft body effect. Then set goal weights, and it looks realistic. If You like to know more, inform me. I apologize also if I sound a little bit unkind. Best Wishes.

        • Hi Adrian, sounds interesting. I would be curious to see it!
          As with all things Blender (or 3D in general), there are many ways to do it. Depends on the context which method is the right one. You can also use physics to get a realistic result, if you want.

    neato, thanks : - very useful for many things - can you suggest some kind of randomizing expression that can be combined with this to automatically randomize the swaying across thousands of plants and grass blades?

    Jan one question, when you want to animate a field I'd like it to have a slight random offset per plant based on its x&y position plus control via wind is this possible?

    • Hi, hmmm that sounds complex. I guess you could bake the expression to keyframes first and then do some physics wind simulation and blend the two together? Honestly I would just use a different method in such a case than an expression.
