Viewport’s References

A lot of people find the human hand to be challenging to model or block out (form) in a way that looks realistic. There are many ways to bring an image into Blender but when it comes to modelling the hand, this is the only method that I know of that can help and the good thing about it is that it doesn’t matter where you are in the viewport. In the example below, I zoomed into the hand from that angle and placed an empty object (Shift + A –> Empty –> Image). From there you can drag and drop the image into the border of that empty object or manually load the image in the properties window.

Don’t forget to check “Align to View” immediately after you placed the Empty

If you have some basic drawing skill, what you can do is sketch out the form/shape of the hand and use it as a guide. This same steps can be repeated for the foot.
