Htoa Traceback error

[p.hafellner]

Hi

when I create a geo node I get this error

Traceback (most recent call last):
  File "C:/Users/Phil/htoa/htoa-5.3.0_r233605f_houdini-18.0.499/htoa-5.3.0_r233605f_houdini-18.0.499/scripts/obj/geo.py", line 3, in <module>

    node.parm('ar_matte').setExpression('ch("vm_matte")')
AttributeError: 'NoneType' object has no attribute 'setExpression'

and the Arnold tab of the geo stays empty, adding the attributes manually doesn't work

in a different post, there was the suggestion to disable sidefx labs but that's no option for me

thank you for any help!

This kind of thing is almost always an environment problem.

So, check

• houdini.env, or if you use packages, the json file
• Help > About Houdini > Show Details

Remove other stuff and make sure HtoA works. Then add back the other stuff.

I am using the .json file in the packages folder I am under MAC OS Ventura MAC M2, still hav the same issue, Arnold loads fine but every time I try to use Arnold I get the traceback error.

i removed every other packages,just keeping arnold. and the env file is very clean. still getting this error..

[stanleyxavier_contact]

finally after lots of try figured it out..one of the geo was causing that error..when i deleted that subnet everything worked..i had a back up of the project..i simply took the subnet from that backup and put it in the current hip file and it worked..
