I've been working on a setup to release sand from a rest position similar as seen in the first 13 seconds of this movie:


Made sure clumping is properly distributed by setting the attractionweight attribute.
Using POP awaken to get the simulation started. So far I get a very even drop of all the grains.
I am looking to get a more gradual release, with some stragglers causing fine streams after the bulk of the grains dropped as seen in the video above.

All suggestions welcome.

@SteveS_66 would you mind listing the nVidia driver version you are using?

Thanks paulcorfield.
I've added to houdini.env file & seems to have fixed the issue (see updated copy of houdini.env below)


# Houdini Environment Settings
#
# The contents of this file are read into the environment
# at startup. They will override any existing entries in
# the environment.
#
# The syntax is one entry per line as follows:
# VAR = VALUE
#
# Values may be quoted
# VAR = “VALUE”
#
# Values may be empty
# VAR =
#

# Example:
#
# HOUDINI_NO_SPLASH = 1



HOUDINI_NVIDIA_OPTIX_DSO_PATH = C: /Users/…/Documents/houdini17.0\optix

HOUDINI_OCL_VENDOR = NVIDIA Corporation

HOUDINI_OCL_DEVICENUMBER = 0

I actually downloaded Nvidia optix the other day to see if that would help, which explains what was the last line of txt on the houdini.env file before I added the txt you provided below it. Not sure if having optix helped or not & not even sure if I needed to download or not.

I opened up the same file I got the message on the other day to test & no message so hoping that has fixed the issue. Thank you again. Legend.

Still seems to be an issue for my setup: Win10 64bit, Nvidia 970.
