Rez use powershell to render houdini will lost $HIP and $F

[zclongpop123]

I used rez on deadline render, and command args has an output path with $HIP, rez will lost $HIP on render path.

Look at the -o in the log

Hi @zclongpop123, can you tell us more about the problem please? I'm not too sure what you mean by "will lost $HIP and $F". Also, can you tell us which shell rez is configured to use (cmd, powershell, pwsh, etc)?

[zclongpop123]

OS Windows 10
Rez version 3.0.0
Rez python version 3.10.11

Powershell

"'$HIP/Render/Snow_interaction/TEST/snow_interaction_02/v002/snow_interaction_02.$F4.exr'"
->
"'/Render/Snow_interaction/TEST/snow_interaction_02/v002/snow_interaction_02..exr'"

$HIP shuld be trans to /path/to/hip_file_folder
$F4 shuld be trans to 0001, 0002, .... 0999,

My render image path shuld be:

W:/projects/sngx/misc/users/jiangmingyao/Snow_interaction/Render/Snow_interaction/TEST/snow_interaction_02/v002/snow_interaction_02.0001.exr'"

but powershell can't push $HIP and $F4 in to houdini ！

@zclongpop123 Just to be clear, does running hython with the hrender_dl.py script correctly resolve $HIP and $F when rez is not used?

[zclongpop123]

Working well on rez and cmd， but Rez and powershell not working.

[BryceGattis]

@zclongpop123 Feels like it could just be a PowerShell issue. Have you tried just rendering on the farm in PowerShell and without using rez? I know the "$" character is generally used in PowerShell to interact with variables, so maybe it's just PowerShell evaluating the "$HIP" variable and doesn't actually have anything to do with rez?

[zclongpop123]

Yes，Powershell will kill $, but when we use rez and houdini ，how to make it normaly.

@zclongpop123 https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_special_characters?view=powershell-7.4

I'm no PowerShell expert, but it looks like PowerShell uses the backtick character as the escape character.

Can you try using the backtick character to escape the "$" character?

So you would pass `$HIP instead of $HIP?
