  • Specific Way to Draw for spine animation?

Hi everyone,

I have been animating a lot of my characters lately and have started to wonder if there is a specific way to draw my characters, specifically at the joints. When I rotate my characters limbs sometimes they work great together with the meshed body parts and the weights but other times they deform and take a lot of work to look sub optimal at best.

Is there a specific way we should be drawing before importing our sprites into spine. Should I be drawing through with my limbs? Meaning drawing my bicep further into the forearm or into the shoulder?

Also should I be trying to draw my limbs specifically at the joint more circular so that they dont stick out on the sides?

It depends on your style, some general rules are:

  • draw also what's covered by another piece (in case the piece in the front moves)
  • try to draw the joints rounder, in alternative you can draw them as a single piece and deform them with meshes (depends on the style)
  • don't draw something that should be behind and above another image on the same level (e.g. the hair above and behind the face, because it can obviously need to be split in two separate layers)
  • if you can, draw the piece straight instead of oblique, as it will take less space on the atlas this way

(I'll add more tips when they come to my mind)
If you want to post a sample of the joint that is giving you problem I can try to help you (:

I had trouble uploading my image. The attachment said my image was invalid after I emailed it to myself from a picture I took on my phone. Anyways my shoulder had a sharp edge and I think I need to make the joint rounder. Also when placing bones in the joints themselves should the very center of the bone be placed in the very center of the joint so the rotation of the bone matches the specific rotation of the joint?

Regarding shoulders when you raise the arm they'll probably look broken, a little trick to add volume is at 02:04:05 of this video:

It depends, but placing the bones in the center is generally a very good idea.

Can you explain this point a little bit more please?

Hi the_terrible, I mean this:

The same spear will take way less space if drawn straight instead of tilted, this is a way you can optimize atlas space.
