UV missing on alembic export Nov. 24, 2022, 6:40 a.m.

I also encountered a similar problem.

In `rop_alembic -> Geometry -> Additional UV Attributes` add `uv*`.



This way all uv can be output to the abc file.

It's probably because the "i@my_id" needs to be a prim attribute not point. (you can promote it after your copy to points)
Vellum constraint properties runs over prims, so it cant find your id attribute



Thank you for your reply. I tried to add "attribute promote", but it still doesn't work. Is there something wrong with my "attribute promote" setting?

You could activate Use VEXpression. Add a custom id to identify each sphere, and supply an alternate value to restscale over time.
if(i@my_id==0){restscale = fit(@Frame,1,48,1,10);}
if(i@my_id==1){restscale = fit(@Frame,1,56,1,4);}
if(i@my_id==2){restscale = fit(@Frame,1,60,1,30);}
if(i@my_id==3){restscale = fit(@Frame,1,24,1,9);}
if(i@my_id==4){restscale = fit(@Frame,1,72,1,17);}

According to the idea you provided, I first defined the id attribute for each sphere.

And then set different restscales according to the id attribute through VEXpression in slover.

But the result does not seem to identify "i@my_id>4", may I ask why?


Looking forward to your reply
