How to output full compiled shader code from matc?

[EnviralDesign]

Hi, I'm trying to use matc from the latest release to simply generate a readable fully encapsulated shader file. I'm trying to learn how all of the various pieces of shader code found through out the github repo actually look when all setup.

The generated filamat file is binary, so I'm unable to find a way to read that.

I can get [some] of what I'm after by using the print flag on windows cmd (-t) and outputting that to a file, however the results are truncated no matter what combination of other command line settings I try. The number of lines it gets cut off at varies as well from execution to execution.

Here's the command I'm using currently:

"C:\Users\envir\Downloads\filament windows\bin\matc.exe" -p desktop -a opengl -t -g -o "C:\Users\envir\Downloads\filament windows\bin\materials\default.filamat" "C:\Users\envir\Downloads\filament windows\bin\materials\default.mat" > "C:\Users\envir\Downloads\filament windows\bin\materials\stuff.txt"

Are there any more direct ways to accomplishing this?
Thanks!

You can use the tool called matinfo to dump each shader contained in a compiled material file.

thank you! I figured there might be a more direct route.

matinfo is more useful because it lets you specify the target shading language, the shader stage, and the variant.

pretty awesome, I am still having issues, though I believe I am missing something simple.
I am running this command:

"C:\Users\envir\Downloads\filament windows\bin\matinfo.exe" "C:\Users\envir\Downloads\filament windows\bin\materials\default.filamat" --print-glsl=0

However, all I get back is this block every time:

Nevermind, I see what I was doing. arguments before the final file!
