hello
On a multiparm hda to unity, I'm using path deform with several meshes. I can play with scale, curve offset etc. I need to know the start & end of each meshes in % of the curve. I want to expose as read-only to the user those start & end values.
To do that I expose two values of uv promoted on detail, during a for each loop.
So I use 2 points, read uv.y values for each and send them to detail.
Details seem to store only the last mesh values inside the loop, I can only see the last mesh
On single pass of the loop, it's good.
I do not know what to do…
Thanks for your help.
Detail attribute 'stored' on for each loop

I've replaced my promote to primitive instead of detail.
As default value on my multiparm for ‘start’ I use :
prim(“/obj/geo1/subnet1/Area”,1,“start”, 0)
& for ‘end’, because primnum is never the same, so I cant give a direct number of primitive
prim(“/obj/geo1/subnet1/Area”,`nprims(“0”)-2`,“end”, 0)
but it stuck to 0, I've made a simple print and value `nprims(“0”)-2` is correct. This value change from a previous loop that refines my meshes.
I cant use `nprims(“0”)-2` on this kind of expression?

seems prim(“/obj/geo1/subnet1/Area”,`nprims(“0”)-2`,“end”, 0) is not updated.
If nprims change, it's not updated on the multiparm target hda
using those gives the same result 0, but on output console it's fine
prim(“/obj/geo1/subnet1/Area”,nprimitives(0)-2,“end”, 0)
or
prim(“/obj/geo1/subnet1/Area”,`nprims(“0”)-2`,“end”, 0)

I'm sorry to bother you with my problems but I feel lost.
here are my steps
capture points : group create -> 2 `npoints(0)-2`
create uv :
aw ->
int maxpoint = 3;
if (@ptnum < maxpoint || @ptnum > (@numpt-1) - maxpoint)
{
@start = @uv.y *100;
}
promote point to prim
capture my values:
aw ->
float mystart = prim(“op:../promoteStart”, “start”, 0);
float myend = prim(“op:../promoteStart”, “start”, nprimitives(0)-2);
I've attached my scene
my values are good and react on the console, but only for the current mesh.
I use the same prim function on ‘default value’ on a float on my multiparm on hda, but same as previously: result 0 :/
