Luban has bricked older versions of itself
A while ago, Luban made it so you couldn’t process any mesh that is kind of big unless you pay. So I just stuck with the old version. Well now my old version doesn’t work at all. I try and open it and it just says download the new version. They’re forcing you to pay for it if you want to use a moderately detailed model.
I got it when it was free and it worked fine then. They released it with the ability to process large models for free. If they want to have new versions with better features that is paid for fine. I’ll pay for the new version if I want those features, but don’t break my old version just because you want me to pay now and decided to alter the deal.
