Hello, everyone.

I have an HDA that takes an FBX, does some poly reduce and uv stuff, and exports a new FBX.

I am using the “gamedev extract filename” sop to get a filename as a detail attribute, but when I try to use it in the output FBX rop, it is not working.

This is what I am using in the Output File field:
$HIP/Assets/Optimized/Geo/`details(“../CD_diva_optimize1/get_filename”,“filename”)`_optimized.fbx

Can anyone help me with the syntax?
Tks in advance

Try “detail” instead of “details”. You also need the index:

Thanks, mrCatfish, but I researched and that one is for attributes with float values, in my case it's a string (a filename).
Strangely, I opened the project on my other pc and it worked as is! Go figure…

As I see it you were doing the right thing so that's why it worked. There is a lot of confusion here as there are two different expression functions "detail" and "details". The last one works with strings and have a different syntax (no index value).
