problem with redshift proxy export May 16, 2023, 12:06 p.m.

The node you're using to export the proxy needs to have it's display flag on. I've run into this before.

Rotation... before, during and after simulation oddness May 16, 2023, 10:43 a.m.

Hi all,

I'm doing a simplified "falling pebbles" simulation, using packed cubes as rigid bodies through a pop source, then using @instancefile after the sim to replace the cubes with rocks... Works a treat, but rotations (or display of) are a bit screwy.

Using @orient to randomise the rotation of the cubes before simulation, the simulation and dopimport stage seem to display rotation slightly off, bit when I copy to points the original master cube after the dopimport to check rotations it looks correct.

Going a different route and using a randomised @N and @up the sim and dopimport match the initial setup visually, but the copies now won't match their rotation to the incoming data... Unless I unpack first in which case I obviously get 8 cubes for each input.

Is the display thing with @orient a known gotcha? (not known by me obvs). And How would I go about making the @N & @up route match at the end?



Constrained collision objects April 18, 2023, 11:16 a.m.

Hi all,

I've noticed an object that gets it animation from a constraint (path in this case) affects flip much more than a simple object level animation doing the same move.

I'm assuming the object and sop level animations are correct as they match, and the constrained one is wrong. I know constraints are a bit different in H, should I steer clear of using them in cases like this?




I've actually got this the wrong way round... The sop level animation is the odd one.
