I'm looking forward to Palworld models popping up on Models Resource or the like so I can do some comparisons on my own. That Azurobe model literally just looks like 3-4 mons thrown into a blender.

Don't know about Tiktok, but this site seems to work for IG to some degree:

Don't know exactly how much it captures, but you can toss the page it gives you into archive.ph at least.

I always just thought of it as, the uppermost bit is that power of two but negative. So for four bits from right to left, if they're set to one you add 1, 2, 4... -8.

Thanks, you saved me a click.
