Hi,

Path mapping in Solaris is not working as we expect.

We are trying to render on the farm and we are looking for a solution that would allow us to render Windows created Houdini scenes on linux render nodes.

I added a path mapping to the HOUDINI_PATHMAP environment variable such as :

os.environ['HOUDINI_PATHMAP'] = "{'/mnt/vol1', '//sledge/vol1'}"

As you will have guessed, those two point to the same network share, the /mnt/vol1 is for Linux, the second one if for Windows

I then start Houdini on Windows

In the /obj environment, I create a file node. I can use a filepath like //sledge/vol1/somegeo.usdand it loads fine. I can change the filepath to /mnt/vol1/somegeo.usdand it still works, which shows that the path mapping is working as expected.

If I head over to the /stage and create a reference node, I can use the filepath //sledge/vol1/somegeo.usdbut not the filepath /mnt/vol1/somegeo.usd. The same issue arises with 'sublayer' nodes

Is there any reason for this ? Could this be fixed ?

PS: I'm going to submit this to the official support, but I'm interested in any community answer too.

Tested on Houdini 20.5.410, on Windows 10
