Im trying to create an animated backdrop that creates a similar effect to the noise-like textures often used in Illustrator or Adobe after effects. Is there a simple and easy way to achieve that in blender;

My current methodology is to create a frost glass vertical plane at the front (to soften the effect - and add grain-like effect) and place a voronoi texture behind that which is going to be animated; illuminating onto the front glass;

I will link a video to show what Im going for approximately https://streamable.com/xj0vz7

What Im doing kind of works, but Im interested to find out whether this is overkill and theres other better ways to go about it;

PS. Yes, I just started Blender a few days ago, complete noob.

Thanks for your time.

You can get something close to what you show with a Noise Texture plugged into a ColorRamp. Also mix a Musgrave with the Texture Coordinate into a MixRGB in order to twist the spots a bit. Then animate the Mapping on the Z location (or, as Allen Simpson says, switch the Noise Texture to 4D and keyframe the W value). If you want some grains, do it in the Compositor, see this answer:

You could also make it more complicated and mix several of these effects with a n&b musgrave as factor...

  • $\begingroup$ Noise texture also has a 4d option which gives you a W value for changing the noise over time instead of moving it through space. :) $\endgroup$ Jan 7, 2022 at 21:30
  • $\begingroup$ @Allen Simpson oh you're right I always forget the W value, I'm going to edit $\endgroup$
