$16 for a *very* non-performant material? If this was intended for use in high-detail scenes, not meant for gameplay, one would generally just use a flipbook animation, or looping HD video texture (both of which are higher quality and available for free all over). I love options, but c'mon, that's pretty steep. $5, maybe. And you can loop in materials, using custom HLSL nodes. Also, there are better ways of doing this, all around. Somewhere on the forums, Ryan Brucks (of Epic fame) himself touched on this. I've personally been working on a cool water material (not "material blueprint", thankyouverymuch) and utility functions, and am close to the quality achieved here, sitting at ~180 instructions with everything "turned on". The kicker? It's pure procedural. No textures are needed. So this is cool, no doubt about that. In my humble opinion though, it's not "good". It doesn't run fast, and it's more complicated than it needs to be.
Lee is right - you can use a gradient effect when you vertex paint in your chosen 3d modelling platform (I've done it in max), meaning the wind effect shifts from nothing to maximum along the length of the leaf/branch/whatever.
I'm fairly certain you can vertex paint the bottoms of the foliage and control the movement using vertex colors along with the wind node. I did this in an earlier project and was able to create a scene with grass that moved less and less as it went down until stationary. I created the grass and painted the vertexes black to red (bottom to top) in Maya.
Take a look at a touching story told at Kotaku. Last week during the Game Developers Conference’s postmortem for Diablo, Shivam Bhatt, one of the fans got an interesting idea while asking a question at a Q&A session.
I asked a question about Battle.net and while he answered, I started checking my wallet
Then, he counted 40 dollars — cost back in 1996 and, in front of the GDC attendees, he told Brevik that he was going to pay for the copy of Diablo he pirated in 1997.
I was 16 years-old, and my friend had gotten his first ever CD-R drive (1x). It took something like 4 hours to copy a game or music CD, and the discs themselves were hella expensive. We were just excited to try it out.
My friends and I used to drag our PCs and monitors to each others houses for LAN parties, and we didn’t always have the games that everyone wanted to play, so boom, we learned how to copy games to play. Diablo was part of this trend, because Battle.Net meant not having to lug our boxes around. We were all huge fantasy fans, and Warcraft 2 fans, so the idea of a new Blizzard game that was like D&D was just incredible.
As high schoolers, we didn’t all have much in the way of money, and my mom wasn’t about to buy a game like Diablo for me, so copying was the way. It was one of the first games passed around my group like this.
Bhatt told Kotaku that the friend who first lent him the Diablo disc passed away of cancer. Diablo was their favorite thing to do together. So, Bhatt thought of this payment as of a great way to pay tribute to his friend.
It wasn’t planned, it was just spontaneous act to honour old friend. It is never too late to do the right thing
