Guide on adding a new model, animation, and creature to HoMMV

Apparently, everyone has their own interests 🤔. But seriously, I've been using "uBlock Origin" and "Firefox" for about 8 years now, and I haven't had any ads or pop-ups.

That's how it should be!!! (but in this case, it's not necessary)
I'm looking at the screenshot and notice that your 555_new.gr2 file is only 165 KB, while mine is 451 KB. Here's a video showing how I convert 555.gr2 (which doesn't open in the program) to 555_new.gr2 and then open it without any errors. If that doesn't help, then I'm out of ideas 😴.

I'm downloading it now, I'll take a look... I use Opera, I'm very used to it, but it still gets through, even though I have the built-in ad blocker enabled... but still, about the Hex Editor and that magic number - why is it specifically that number, and is it the same for all models?

I've checked... it's a miracle, I did the same thing... you just used a different model, or rather, a different skeleton... I used the Titan... but I'll try again now....

It worked... damn, I just tried to open the skeleton like that, not the animation... But how do you open the skeleton in a T-pose then?
