So I'm trying to make grass from 3d motive tutorial. After lots of messing with coord system I finally made it work... kinda... I don't know why but they are rendered with vertex colour. I painted the terrain with detail painting. If I change the tint colour of grass in the terrain settings only the value changes anything…
I'm unfamiliar with the tutorial, but you should definitely be able to animate the grass in the vertex shader according to vertex colour, if that's what you're after. Although, all of the grass vertex animations I've seen use the UVs to control which parts of the grass are affected, and you could probably use your vertex…
Thx! I will try to do it. I never messed with the shaders code though. Must ...useeee....my.... brains! Since when You paint terrain with detail mesh it responds to wind (making this wavy movement) it should be possible. Still have the vertex paint issue though :/ The tutorial uses red channel of vertex paint to move…
