1 - Faded edges
I’m trying to get an effect that has a cylinder with soft edges (ie the ‘edges’ as visible to the camera blend into the background)
I’ve tried to do it with a ‘blend’ texture operating on the alpha, but I can’t get the settings right.
2 - Animating Halos
I want to create an animating in which the ‘lines’ of a halo move from frame to frame, I know that I can acheive this by changing the ‘seed’ of the halo lines, but I can’t set a key on this material variable… any ideas how I can do this, without animating frame by frame by hand?
3 - Particle systems
I want to put together a moving line of particles, with very minor random jitter. Using a single face mesh and a ‘norm’ value of 2, I’ve almost got what I want (although a higher initial speed would be nice), but the jitter
occurs in waves because of the way the particles are emitted from the face. Thus the line appears to ‘pulse’ when animated.
Any ideas how I can make the jitter more random?
Also, if I apply a random speed, that speed is applied in all 3 axes, is there a way to constrain it to being in the direction of the normal?
