VFX – Matrix Code Rain

Here is a little preview of an effect created to give the feeling of matrix trainning code, is a single shader

For the random changing text, I’ve created a texture with random text, organized on a grid with perfect distnaces between each other

Then, by adding a constant offset on Y, and moving a little X on fixed values (using floor node to keep the values fixed) I was able to have a changing letters effect:

Then, I’ve created simple texture of falling lines, where the tip is specially bright, and tilled them making them an inffinite pattern

And using some of the already calculated logic before, I added some movement

Then after multiplying both effects, we have the perfect base:

Now we just need to add some extra passes, combine them, and create a smooth fading on top and bottom of the sahep

And multiply by a color before output the value

So we have this at the end

Now we just need to create a mesh with inverted faces, that fits with the effect of infinite top, but without breaking visually because the culling, and we are done
