It all starts on reddit when the develper of the mod posted a question what should he add to the mod Then u/MilesMossi gave him an idea of an topaz golem that will do what player dicates it.

 The developer thought it was a good idea so he started to work on it, but a problem appeared when he couldnt import the model from blockbench so he just used the silver fish model instead and called it a Topaz Servant.

After the release it bothered him that the silver fish model didnt look good and like its pourpose so he go to the block bench again and after some time he figured out where is the problem and then imported first prototype into the game which looked a little bit like copper golem

Couple Changes and the second prototype was made but the same as the first one, the model animations didn't work properly and it looked reallt cursed

Removing some things from the model and the final version of the model came out but it still had the same issues as the last two, animations didn't work properly

Some changes to the pivot points and rotating the Topaz Golem animations finally worked

Then came the texturing that took surprisingly fast

The mod was released, and after release I noticed that the Topaz Golem had scoliosis, i didnt want to post another version of the mod so i waited to notice another bugs and then post it (to this day it isn't fixed but will be fixed)

And thats the story of Topaz Golem, honestly I'm surprised you've read all of that and thank you for your time :)
