How to use:

1. Extract any .OIV file using 7-zip into a new folder.
2. Put convert.go in that folder.
3. Run go run convert.go.

A new folder named onigiri will be created. Move this folder to your GTA5 installation folder.

onigiri.asi is required to load replacement files from the onigiri folder.
I don't know where else you can obtain this other than downloading NaturalVision Enhanced.

Don't want to compile it yourself?
