>>18336666Hey, I'm another person experienced with Live2D models here, I work closely with another rigger as a Live2D artist.
It's not the competency of the riggers for Cover's case, as they hire many competent riggers (as you mentioned). My partner and I eagerly watch outfit debuts and model reveals for Hololive as many masters in the field do work for them.
It's the competency of the tracking programs they use, since they use proprietary company software instead of things like vtubestudio.
If you compare the range and physics of models in the rigger's showcases and compare it to the movement and physics on the actual streams, you can tell there are major things off. The physics seem to run at a different FPS for one (you can tell with Brain Tsui's use of physics), and the arms for hololive models just... don't move. I'm sure there's loads more examples I can pull up, but those are some of the major ones. You can tell that the riggers aren't particularly being restrictive with their models when you look at the showcases, it's the tracking the company uses that restricts the model grandly.
Subtle body movement can help something look more organic and not look like a stiff png, which a lot of the riggers do implement as seen in the model showcases, but cover's tracking software just doesn't seem to use it.
On top of that, cover provides all the girls with iphones, but its hard to tell if they actually utilize face ID. It's a significant waste if they don't. The tracking isn't as clean as it could be with mouthforms and head / eye movements. Not to mention, they could add cheek puff, mouth x, and tongue out to models which is pretty simple, something a lot of fans would like.
In the end, I think it's Cover not giving proper modern updates to their tracking software. It's archaic and holding back the rigger and artist abilities, and holding back the girls from being more expressive overall. Having to choose minor expressions such as widening the eyes, being sad, being angry, solely from hot keys is a joke.
(However their choices for artists are dubious since not all of the have made models for Live2d before and are therefore inexperienced. I wouldn't be surprised if a lot of the models needed corrections that they didn't get. Even if someone is a great artist, it doesn't mean they're great at Live2d art. Rigging an artist's first live2d model can be hell in a hand basket sometimes. Still, it doesn't beat the rigging showcase vs live model comparisons)
TL;DR : It's not the rigging most of the time, it's the company tracking software.
