HEllo there spine fellas.
We have found a little drawback on the meshes and FFD system in our studio.
When you apply a mesh over a part of a character, you no longer can alter it's color in Spine, this is an issue, since for certain characters, we like to give a little shade to the legs that are further from the viewer to add a little depth, with no necessity of doing that from the original sprite.
Briefly, we recycle the legs and arms , and add a layer of color over them to save some memory, but we can no longer do that due to the bug.
