Batch convert dae to scn

Is there a way to batch convert Collada dae files to Scenekit scn files?

My project uses approx 50 models created in sketchup that are updated regularly, these are exported to DAE but also need to be converted to SCN files for usage in xCode. I know it can be done manually via xCode and "Convert to SceneKit scene file format (scn)" but this take to much manual labour.

I agree with @Hixfield About everything except you need to add one more option to the scntool to get your materials correctly without need to re add all manually

scntool --convert INPUT.dae --format scn --output OUT.scn --asset-catalog-path .

The dot at the end of the command line is very important it means you will set resources to same location

If you don’t set the —asset-catalog-path . You will have no materials

@HixField has a good shell script for invoking scntool. Another way to do that is to leverage Xcode's build system, which does the same thing for any .dae files you put in a project's scnassets folder. Even if you're not bundling those files in your app, you can create a dummy Xcode target or project that contains all the assets you want to convert, and it'll convert them all whenever you build the target. (Which you could then integrate into a CI system or other automation.)

Based on https://the-nerd.be/2014/11/07/dynamically-load-collada-files-in-scenekit-at-runtime/ I figured out that the scntool is able to convert it via the command line and write the following script:

find ./dae -name "*.dae" | while read f ; do 
inputfilename=$(basename $f)
echo $inputfilename
./scntool --convert $f --format scn --output ./scn/$inputfilename
done
for file in ./scn/*.dae; do
    mv "$file" "./scn/$(basename "$file" .dae).scn"
done
