It's very simple because the pieces don't have to have weights painted. In fact, the only Bionicle with flexible parts is the matoran (like Hafu) which I'll do a smooth bind with the arms.
I added a detail map of brushed metal from Google to see how it would turn out and was incredibly satisfied with the outcome. I'm not used to using detail maps, mainly because my final product will be in UDK and thus, the detail will be incorporated into the diffuse as well as a normal map.
Now, there is just one thing missing from Pohatu, and that is the hole for his mouth which I am well aware that I did not include. In fact, when I do the sculpt, I will add it in and bake it into the normal maps. After Onewa, I may take a break from modeling new pieces and texture Hewkii, make a skeleton for the Matoran, and begin the sculpting for the normal maps on the current models. The Maha was for fun, but if I feel like it, I may texture him too. After all, he is a part of the town environment.
Because of how Pohatu is progressing, I am newly inspired for this project and am no longer reaching the end of my rope (doing those pieces individually was tiring). Making the masks and parts for Tahnok will be fun and I am very excited for it. Also, I recently have looked into an article for using gradient maps for UDK instead of diffuse. I am intrigued with this and am considering using that for the Po-Wahi and Po-Koro.

I've noticed that I'm actually getting a lot of readers every time I post a blog and I wanted to thank everyone for the support.
