Can mesh reveal mesh ? as in a scripted way ?

I am trying to recreate this reveal effect in 3d

But not with build modifier or an alpha texture or booleans.

An idea would be like a smarter smoother build, but would still be to jumpy, so I thought that mesh used as an alpha channel for a parent mesh following on a curve might do the trick, since that is basicly how I did it in after effects here

Just use an animated texture.

Or a boolean modifier with an animated mesh, if you want to get fancy (and want to trust the boolean operation).

animated texture is to linear and full of hit or miss. Boolean is way to crashy or slow.

Minus the logo design, this is pretty much what you showed.

It’s even easier if you go with only curves and use UV Orco.
