Character texture hard block edges?

I am even not sure if this is my problem so the image below will explain better

can you kindly explain to me why I am experiencing this? and how to go through fixing this?

Thanks in advanced!

note that I even am not sure if it is texture or not, I just cant understand why I am getting this issue!

I changed the textures and the issue is still there

I’ve had a similar problem and, for me at least, it wasn’t textures. It was caused by having a few vertices in the mesh that weren’t weighted to the appropriate bone (or weren’t weighted to any bone at all). When you do any kind of transformation based on the skeleton, those vertices get left behind, causing these odd looking spikes.

Yeah that’s happened to me too. When binding the skin to the skeleton for some random reason it decided the ear should be affected be the pinky and whatnot and I got results like one’s you have in your picture. It’s clearly a geometry problem, not a texture one like you’ve said.
