yeah the lack of iterator is a bit of a bummer.

here is a really neat color corrector I have been working on.

simple little gem:
a rolloff you can use in your slap comp to get control over your highlights
“` #bind layer src? val=0 #bind layer !&dst
@KERNEL { float4 color=@src; float alpha=color.w; color=1-exp(-color); color.w=alpha; @dst.set(color); }
“`

Here’s the pighead paint cop thing. I swapped all my textures for the brush strokes to ones that i made in cops. and then i’ve also commented all of the paint stroke splatting code. It’s not hyper optimized, this is again a dumb approach where i strictly stay in COPs for everything. It’s way easier and better to do some of this stuff in sops.
if i catch you using this without modification on a commercial project i will make fun of you for forever, and i will ban you from the server 🙂

@jan1376 @flight404 have fun fellas

@eetum you dont need a wrangle, no 😮 but that’s a fun aspect of OCL in cops ive never looked at.
I just whipped up a VAT example for my class, here’s the file. It directly reads attributes from the geometry input.
the file also shows how to read from this cruddy VAT texture to apply the animation back onto the demo geometry (in this case a pighead)!
