I've recently switched to Technic Platform and can't seem to find any ways to add Java args to my client without modifying modpack. What I want to do is set min and max heap size to 4 GB (config in launcher only changes maximal, not what I want). Just two simple args: -Xms4G and -Xmx4G. If I just add them to version.json, it will get overwritten by launcher on modpack verification. What should I do?
