Yeah, really harder :/
While I have decent result with the Intrinsec (Thank you guys for providing
the hip btw) inside a solverSop (on a a low-res testing sim), it badly
behave if I start adding some glue network. Plus isolating / masking the
Solver Solver so that it doesn't affect every other objetc is a pain in the
ass atm.
I tried all sort of grouping as mentionned in the previous thread, it
doesn't work.
I see there is an Object Mask inside the SolverSop but it is stamped in
chinese...

As a follow-up, if you use the vex solution to modify their
transform
intrisic it also works, but with the same problem as before...the geometry
is changed from the SOP Solver, but the collision keeps on using the
original size :p
this is starting to be harder than I thought...
