Tip for Paint Brush: Before starting to paint like I did Make sure to turn Auto Backface Masking on where I switch to the Paint Brush I didn't realized it until later in the video.
This Video covers up how to use Masking Extraction in a simple and beginner way. The same Masking extraction technique could be used for creating clothes and shoes and enhancements to any mesh. PS sorry if the video sucks and if the audio is bad and I'm speaking in a low voice made this when I didn't slept the entire night.
For the tutorial you must know basics like how to use a mask and changing brushes or clear and invert masks etc. More Proper and Detailed Tutorials coming soon.
