Hello world !
Well, I've been trying to make an animation of grass blown by waves of air. I think I'm on a good path :-)
I read these posts where about everything is explained :
http://www.planetside.co.uk/forums/index.php?topic=20339.0http://www.planetside.co.uk/forums/index.php/topic,20353.msg201597.html#msg201597I used a power fractal over the power fractal producing the "wind effect of the blades".
To create waves, I simply increase the feature scale.
I don't want to use mesh displacer because I'd like to be able to move just the leaves of a tree and not the trunk, that's just a first test (moreover there is no mesh displacer for the grass here :p )
Also, as said in the posts linked before, in this case I can't use the ray traced objects as the deformation of the blades is not supported :-/ (only the shadows move, not the model)
It could be looking nice if these horrible "yellow squares" didn't appear...
(see the pictures)
I made different tests, and actually when I renderer with or without ray trace objects, I got this result :
With the ray trace ON
With the ray trace OFF
But, strangely, if I create another population of grass, and copy past the fractals in it, I got this result :
With the ray trace ON
With the ray trace OFF
Could anyone explain me what's happening?
I think it comes from the rendering mode, but I don't understand fully how it works...
I tried to change a bit everything without success, Light, camera, rendering, it comes from somewhere there as when I move the sun, the "yellow squares" move too, but don't disappear
Anyway, you'll find a GIF of the animation here :
