Convert textures into .vpcf file to be used with dry erase boards in Half-Life: Alyx
Drop the .exe in the top directory in your Half-Life: Alyx SDK. Open the directory in the command line and specify the relative path to .vtex texture. This should automatically create a particle system file (.vpcf) for you.
Use argument -help for options.
Example:
> img-to-dry-erase.exe -vtex="materials/particle/dry_erase/my_texture.vtex"
