This is my first time using Arnold for Houdini. I have finally installed Arnold for Houdini with help of Autodesk. I had problems with installation. Now I tried to render a simple scene. I could not. I have a geo,  a camera and a ligth.

this is the error:

Error

ok. Python 2.7 version of HtoA (no ".py3" on the folder names)

C:/Users/caarr/htoa/htoa-6.1.2.1_rb46a0de_houdini-18.5.759/htoa-6.1.2.1_rb46a0de_houdini-18.5.759

Python 3 version of Houdini:

File "C:\PROGRA~1\SIDEEF~1\HOUDIN~1.759\python37

thank you for the reply but I am not sure if I am understanding what you are trying to say. Is it that htoa is using python version 2.7 and houdini is using python version 3. And they should use the same version and if this is the case, then what do I have to do? I see that houdini has 2 folders of python, one is python 27 with only 2 files and python 37 has many files.

[Stephen.Blair]

You need

Python 3 versions of  both HtoA and Houdini
OR

Python 2 versions of both HTOA and Houdini

You cannot have a mix, that won't work.

thank you, I reinstalled Houdini 18.5.759 python 2. Now I can render with Arnold.
