trail, and glow, motion blur

Per's icon

hi!

Im trying to create motion blur with the patch below but dont really understand how to connect the shaders. I would like to make the ball look like some kind of asteroid with a tail and glow.

My question is:
- what shader can I use to create motionblur and trail?
- I been through the tutorials but I cant really understand how to connect shaders. Whatever Im doing seems to be wrong. Can anyone help and explain?

i am sure, that there is more eficent way, but maybe my patch will clear you something :) so first thing to do is to capture the texture (in my patch i used jit.gl.node, because i wanted to capture plane that is already moving). when you get the blue cables, you can do with it whatever you want :) i think, it will be slow in fullscrean.

nice fx & examples :)

In order to better understand the design I'd have to make, I'd like to know what I should do in order to have this fx more 3D friendly.

I mean..
the videoplane is a plane.
in my current system design, I'll have a navigator navigating into a 3D space, looking at some nebula & glowing objects.
if I move around that videoplane, it kills my 3D of course.

What would be the strategy to follow to have this ... 3D friendly?
I thought about reorienting ALL videoplane rendering this FX to be perpendicular to the point of view direction... sounds ugly & crazy.
