Arnold for Houdini 17. Anyone got it to work?

Arnold for Houdini 17. Anyone got it to work?

I downloaded HtoA 3.2.0 from
https://docs.arnoldrenderer.com/display/A5AFHUG/HtoA+3.2.0

Installed also license server from here:
https://docs.arnoldrenderer.com/…/A5AILIC/Installing+RLM+on…

houdini env file was automatically edited by plugin installation. But i cant get it to work.
In houdini there is no arnold shelf and cant add it as there is no such shelf.

The Redshift settings are overriding the Arnold settings.

You need to combine the two PATH lines into one line, and the HOUDINI_PATH lines. Like this:

PATH = "$PATH;C:/Users/ISUther/Documents/Arnold_renderer/htoa-3.2.0_r9e1313b_houdini-${HOUDINI_VERSION}/scripts/bin;C:/ProgramData/Redshift/bin"

HOUDINI_PATH = "C:/Users/ISUther/Documents/Arnold_renderer/htoa-3.2.0_r9e1313b_houdini-${HOUDINI_VERSION};C:/ProgramData/Redshift/Plugins/Houdini/17.0.352;&"

my Houdini env file looks like this:
#
# 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
# htoa config start
PATH = "$PATH;C:/Users/ISUther/Documents/Arnold_renderer/htoa-3.2.0_r9e1313b_houdini-${HOUDINI_VERSION}/scripts/bin"
HOUDINI_PATH = "C:/Users/ISUther/Documents/Arnold_renderer/htoa-3.2.0_r9e1313b_houdini-${HOUDINI_VERSION};&"
# htoa config end
HOUDINI_DSO_ERROR = 2
PATH = "C:/ProgramData/Redshift/bin;$PATH"

HOUDINI_PATH = "C:/ProgramData/Redshift/Plugins/Houdini/17.0.352;&"




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

Note! i do have redshift also installed, but i wanted to try Arnold for skin shaders as i am trying to pick a rendering engine for houdini.

Arnold itself (that installation) is installed to directory as:
C:\Users\ISUther\Documents\Arnold_renderer

Yes, people are using HtoA for Houdini 17. I have it installed and working.

What's in your houdini.env?

What's logged by HtoA at startup?

You don't need the license server to load HtoA into Houdini.
