Hello, everyone!
I had to spend some time to work on the physics of the main character and his android helper (SQ3000 helper).
I will not bore you with a technical description of all the work done, I will only say that I had to make several changes in the bones and body of both characters to achieve the desired effect.

I also had to give up simulated hair. Because in the open world it puts a lot of strain on the video card performance. For this reason, I decided that performance is more important than realistic hair and had to spend some time to simplify the hair structure.
At the moment the main characters in the game are fully optimized and I have found the golden mean between game performance and visual display.
Perhaps I will make some adjustments in the process, but at the moment I'm happy with everything.
The next stage of the work will be to create a customization of the android's appearance so that you can make changes to his personality to your liking. I'm not going to make fine-tuning of the appearance, because there will be a lot of characters for every taste in the game, but I think a small modification will be possible.
The clothes for the android you will create the same as for the main character. For this I think that it will be possible to achieve a great variety.
Right now I'm paying more attention to optimization because it will improve the quality in the future.

I have attached a video file of the android body physics to this post. This site has limitations on showing videos, so I apologize for any discomfort.
If you have any questions, I am happy to answer them. Due to the fact that I had to redo a bunch of objects, I was a little lost, now I'll try to do reviews of the work done more often.
Have a great day! See you soon!
