How to remove all shaders & create a list of all the image maps used in them?

Hello world,
Trying to use hou.find() commands to separate out all the shaders in a hipnc/hdanc file. My goal is to create a list of all the image maps and their locations. So I may then create a convert tool that takes pngs and outputs .rat files to the appropriate locations so none of the paths in the shaders break.

Thanks

You can use the opextern hscript expression to see all external file references on a node (eg hou.hscript(“opextern” + node_name)). Then it's just a matter of running that on each shader in the file.

Hi, you could also use something like this in Python, try fo filter for certain extensions

def getFileRef():
    import os.path
    import hou
    refs = hou.fileReferences()
    cleanedRefs = []
    #check all filereferences amd return a list of attributes
    for ref in refs:
        refAsList = []
        if ref[0] != None:
            parm = ref[0]
            fname = parm.eval()
            valid = os.path.isfile(fname)
            fileextension = os.path.splitext(fname)[1]
            refAsList.append(ref[1]) # file reference
            refAsList.append(fileextension) # file extension
            refAsList.append(valid) # file on disk?
            refAsList.append(fname) # resolved path
            refAsList.append(parm.node().name()) #owner
            refAsList.append(ref[0].path()) #parameter name
            cleanedRefs.append(refAsList) parm
    return cleanedRefs

for item in getFileRef():
    print item
