Sepu

You can do it pretty much the same way as Mantra, but you need to make sure to uncheck "non-blocking current frame rendering" in the Rop main tab

you might be running out of RAM, also what version of RS are you using? Also, go to the Redshift Menu > PLugins options > Debug and check Verbose so you can see what exactly is going on. One more question what drivers are you using and system Specs? But yes if you put you post in RS forum Juanjo will help for sure with the log.

Vellum + Bullet do not work together yet as far as I know unless they added support for in one of the latest builds.

you mean instead of going to the positive Z you want them to go negative? if so just drop a point wrangle and add. Btw I wouldn't use the point sop is deprecated. @N = {0,0,-1}; Depending on what you want. @N = {0,0,1};

the add and if statement ... if(@density == 0) removepoint(0, @ptnum); or you could save img and use in the density texture.

use the density attrb instead in the scatter and put Cd or density

Dont need a foreach, just add a resample, dont need to resample anything just make sure to check the curveu attrb. Then in a wrangle. f@width = chramp("myRamp", @curveu); add a polywire and use the attrb @width. You can add a fuse as well if you wish to.

import to Houdini Alembic ROP or Alembic archive > unpack > Convert Then scatter points and use the fracture tool.

Not sure about your setup, but here is working RS_.hipnc

do not use the backticks.

Here is one way, You can control the ramp so you can affect where you want to add the noise, etc noiseWires.hipnc

point replicate, copy and transform or use a transform and merge it back?

if you check your collision geo you will see why, anyway here is a fix. OKP_waterPour_v03_fix.hipnc

You need to bring your attrb into Vops here is a fix version, if you need a reverse add a fit range. color_extrude0_fix.hipnc
