For things like these and to integrate these issues into a pipeline I usually write a couple lines of python to convert all files in a directory... Is that what you meant?

Copied from one of my scripts, you'll have to test and change stuff to make it work for you. Quick and dirty... I have this being executed from maya and have maya push data about the current asset  into the script to determine where the textures are located etc. This is a stripped version...

    cwd = os.getcwd()
    if not os.path.exists( cwd.replace( 'tif', 'tdl' ) ):
        os.mkdir( cwd.replace( 'tif', 'tdl' ) )

    allFiles = os.listdir(cwd)
    
    for file in allFiles:
        if file.endswith('.tif'):
        
            src = os.path.join( cwd, file )
            dest = os.path.join( cwd.replace( '/tif/', '/tdl/' ), file.replace( 'tif', 'tdl' ))
            print src, dest

            if 'COL' in file:
                cmd = "tdlmake -byte -colorspace srgb -newer %s %s" % ( src, dest )
                os.popen( cmd )
            else:
                cmd = "tdlmake -newer %s %s " %( os.path.join( cwd, file ), os.path.join( cwd.replace( '/tif/', '/tdl/' ), file.replace( 'tif', 'tdl' )) )
                os.popen( cmd )

and yeah, I know that there are a couple things you could do nicer in the code :)

edit: Did I get you correctly at all? What do you mean by converting multiple files into one file?

Hehe, yep. I have a button in Maya that converts the textures for the currently openened asset and thats just easier to do in Python,- at least for me. It also changes it's behaviour concerning colorspace according to the texture type. I am sure you can do that in zsh too tho. :)

Hehe, just to defend myself: On a decent OS, Python comes preinstalled ;)

thanks all

i am using windows so ...

@aghiles i guess the batch code has to be

for %f in (*.tif) do tdlmake.exe %f %f.tdl
instead of %i

@ leeway ill def give it a try...

Hello everyone,

I was wondering if you have tried to do this on a mac, I'm trying this: for %%f in [*.hdr] do tdlmake %%f %%~nf.tdl

But no luck, any ideas?

Thanks

Thank you Aghiles, Moritz,  it works like a charm.

Cheers

Well for what it's worth, I'll show my solution to the problem. Of course, it's python ;)

I found it necessary to add different options to different files, e.g. 32-bit displacement maps as a "linear" colour space, and an 8-bit colour map as "srgb" colour space. And my solution needed to "scale" well too, which I think it does, it works just as well for 10 files as it does 100 files.

My solution was to enable the directory name under the "<project>/sourceimages/" directory to guide the options automatically given to tdlmake. Note: Only files in "<project>/sourceimages/convert" are converted to .tdl, this seems a cleaner approach than converting all files under "<project>/sourceimages/*". All the output .tdl's are located in "<project>/sourceimages/". For example, accessing the textures is as simple as "<project>/sourceimages/texture.tdl" in a shader string parameter.

So the file "<project>/sourceimages/convert/srgb/colour_map.png" will automatically be given the "-colorspace srgb" flag, and the file "<project>/sourceimages/convert/float/linear/latlong/hdri_map.hdr" will automatically be given the "-float -colorspace linear -envlatl" flags.

It's basically a remapping of tdlmake's options into a directory tree.

You can download a tar.gz with the .bat, .sh and a list of "options"/directories from the link below.

Have fun :)
