Point String Attribute to a FILE_NAME in a FILE SOP

[Anatol]

Hi guys.

I have a point with an attribute @mesh_path

@mesh_path = "/mnt/projects/model/mesh.001.proxy.OBJ"

and File SOP connected below

I can't read file if I use attribute in a FILE_SOP text Field.

`@mesh_path`

Is there any possibility to use string variable in FILE SOP text field to read the file?

What you can do is place a Python node before the file node and simply assign a string to the file parameter of the file node.

file_node = hou.node('/obj/geo1/file1')
file_node.parm("file").set("/Users/artist/Desktop/cell_sequence/ap_cell_sequence_001.obj")

You may not even have points before a file node, if you think about it.

Use point/prim/detail expression. Something like `details("../null1", "attributename")`. Using "details" instead of "detail" returns a string, it's the same for the point and prim expressions.
