Finally calling it done. First time setting anything up on UE5. I used UE4 for a couple past projects, but that was more just basic rendering. Here, I learned about camera, lighting and even terrain creation.

Not much of a fan of rigging. I can kinda do it, but I'll always let a program take the first swing at a character and prefer to do the clean up afterwards. 
Glenn was done completely by hand (never again)
Other characters were tested in Mixamo, but still done by hand because it just wasn't there yet.
But I'd heard good things from Rigging buddies about AccurRig and decided to try it out for this project. 
And, it's not bad. I needed to add some simple 'arms' to Giga Gaia, because the program didn't like the gap, but that was the only error I got. Assigning points was easy, and I liked that you could mask off points (like GG's lack of legs), so that the bones didn't get randomly assigned. Also, the weight painting on the fingers was soo clean and tight. I love it. That's my most hated part to do.
GG just needed a bit of cleanup in Maya, but I owe that to the oddness of the creature. 

Slowly getting there.
Learning landscape sculpting. I bought some materials from ​AleksandrIvanov on the Unreal marketplace. Love they way they look for the ground. Just need to learn how to use and paint them properly. XD

Got Giga Gaia through Substance and into Unreal Engine 5.1. Rigging still needs cleanup, but I'm excited about being able to pose it in engine, as well as using blendshapes. 
Still focusing on setting up lights, since it's such an epic scene. 
Frog is even making an appearance. He's one of the first characters I made when learning back in 2020. He's getting a full re rigging, because oh man. I can tell he was one of my first characters. Looking at his UVs makes me cringe. XD
