2. Yujiro is the first character in Tekken 8 who can lift just his big toe. Personally, I found this the most interesting part. Tekken 8 characters are actually built so that they can’t raise their big toe on its own. That’s because all the toes are bound to a single bone, “L_Toe” / “R_Toe.” That’s what makes Yujiro’s intro so interesting. They wanted to recreate the scene from the manga perfectly, so they found a way to make his big toe lift. You might think this isn’t a big deal technically. But they must already have an established body setup for Tekken 8 characters, and they were willing to step slightly outside of it just to recreate this one scene. This points to two possibilities: either Yujiro’s bare feet have a dedicated shape key for toe movement, or his bare feet alone have their own toe bones and weights. Of the two, I think the first one is quite likely. They don’t usually like relying on shape keys, but Yujiro is a manga character. His proportions are unusual, but above all, recreating his exaggerated facial expressions couldn’t have been easy. So my guess is that they combined facial wrinkle blending, a few shape keys, and bone-based facial animation. If so, they could have made an intro-only shape key for the toes at the same time. If they didn’t use shape keys for the face, they’re absolute madmen. That would mean they recreated those unique, complex expressions with nothing but bones and textures. Either way, what they’ve produced is already incredibly impressive.

The teaser trailer alone already reveals some pretty interesting things. But rather than leaving it to people’s guesses and gut feelings, I’d like to share some more accurate and interesting facts about Yujiro. 1. Yujiro’s body shares the UVs of Tekken 8’s common basebody. Identical UVs strongly suggest that the topology is also completely identical. Take Clive as an example: although FF16 assets were used, his basebody topology and UVs are shared with the rest of the Tekken 8 cast. That’s exactly why Clive can also use so many of the common items. The developers have a very robust in-house proportion system called “PRP + MSL,” and with this system alone they can deform the male body mesh at runtime to match the proportions of almost every male character. For example, the common male basebody can be deformed into a perfect fit for Jin, and it can also be matched perfectly to the proportions of Jack-8 or Fahkumram. All from a single model. I keep stressing this to people over and over, but in other games, proportions are usually changed only through shape keys or bone scaling. Tekken 8’s proportion system on its own, however, can produce a huge variety of body shapes. In other words, Yujiro follows the grammar of Tekken 8’s character design exactly, so he fits into TEKKEN 8 perfectly. Of course, he has never appeared in a game with AAA-level graphics like this, and since the original source is a Japanese manga, they would have had to design the character from the ground up. Some might argue that Yujiro’s proportions are so exaggerated that they couldn’t have used Tekken 8’s existing body. No. As I explained above, the male basebody model can even be fitted to Jack-8 at runtime. You won’t be able to refute this just by glancing through the files in FModel. I’ve actually used their proportion system to complete a Homelander costume mod for Jack-8. It really works, and it’s an incredible system that cuts the game’s file size by at least half, maybe even to a third. Also, arguing that his skin color is different is simply absurd. The skin material can produce many different skin tones from the same texture by blending in a Skin Color Tint. In conclusion, Yujiro’s body was built on Tekken 8’s common male topology and textures, so you should be able to try modding experiments like applying Yujiro’s body texture to other male characters. People who enjoy simple swap mods may well start churning them out on day one. More in the thread below
