[SOLVED] Redshift :: Missing Shader Kernel

While going through Entagma's rendering tutorials, everything was working fine until I realized the RS MAXON NOISE node wasn't available in the version being used, so Redshift and Houdini were upgraded to v.3.0.26 and v18.0.532 respectively. The tutorial was restarted from the beginning but the renders are now entirely black.

Digging into the Program Data folder exposes the GPUKernels folder and its subsequent content are missing. Uninstalling and reinstalling Redshift hasn't helped; nor has rebooting my workstation.

I'll certainly reach out to Redshift, but since it's a Sunday, figured too see if anyone here knows how to remedy this in the interim. Thoughts?

Houdini 18.0.532
Redshift 3.0.26
Win10 Pro
Titan X GPU
Bunches of RAM
Lots of HDD
Ikea Desk: Effectiv
Subaru Crosstrek '18

Updating my Nvidia driver to v.452.06 fixed it.

Thanks, for anyone stumbling here after a few hrs of redshift begginer here's the setup version for dummies

1) Redshift does not work on houdini apprentice, go buy that indie license!

2) Get the latest version of Redshift that matches your version of houdini, starting on houdini 18.5 you should also install the solaris version, these are not always bundled in the latest download for the website, but rather go to the redshift forums and look for your houdini version , there's usually a blogpost by de developers with the latest plugin versions, that's the one you should copy to your plugin directory of houdini

C:\ProgramData\Redshift\Plugins\Houdini

and

C:\ProgramData\Redshift\Plugins\Solaris

they are two different folders because redshift considers them two different pluggins..


4)If you followed those steps go to :
C:\Users\ZEUS\Documents\houdini18.5

and open the houdini.env file in a text editor and append the following at the end :


HOUDINI_DSO_ERROR = 2
PATH = “C:/ProgramData/Redshift/bin;$PATH”
HOUDINI_PATH = “C:/ProgramData/Redshift/Plugins/Houdini/${HOUDINI_VERSION};&”
PXR_PLUGINPATH_NAME = “C:/ProgramData/Redshift/Plugins/Solaris/${HOUDINI_VERSION}”

do yourself a favor, don't manually enter the version on these just copy and paste that and if redshift doesnt load go get the right RedShift version for your Houdini


5)Update your nvidia drivers

Enjoy.
