HI, It's a pleasure to play with NormalUVModifier, I'll soon have my Sound-Clay interface working. But I've just seen that the faces are inverted (because I disabled bothsides):
my bumpmap is a greyscale bitmapdata : bumper=new NormalUVModifier(Mesh(rain),bumpMap,50); and when some event occurs : bumper.update(1,"r"); Are they some ways to invert that or did I do something wrong ?
