Automate File Naming Convention?

[bentraje]

Hi,

Is there away to automate my Output File parameter in ROP FBX Output node based on the Geometry File parameter in File node?

For example,
Input: Geometry File: D:/chair_big.fbx
Output: Output File: D:/chair_big_fixed.fbx

I have a lot of these fbx files that needs fixing and it would be nice if I can just swap them out and click save disk rather than changing the output file everytime.

 I can use the copy/paste relative reference but there is the "_fixed" suffix that I don't know how to insert lol

Throw this in your Python Source Editor and run it:

import hou
import os

fbx_rops = [f for f in hou.root().allSubChildren() if f.type().name() == "rop_fbx"]
if fbx_rops:
    for rop in fbx_rops:
        outparm = rop.parm("sopoutput")
        if "_fixed" not in outparm.eval():
            basepath = os.path.splitext(outparm.unexpandedString())[0]
            newpath = basepath + "_fixed.fbx"
            outparm.set(newpath)
