I am fairly new to blender coming from a 3ds max / Maya background and I'm trying to Unwrap my frog model.

I have made UV seams on edges to split up the UV islands, but when I unwrap it just messes up all the UVs, as shown in the image.

I can still unwrap by view, and relax the UV, but its still causing issues right on the edges.

I used unwrap before and it was working fine, I had to re do my model as the legs weren't animating well, but now its just not working at all.

would it being skinned / animated have anything to do with it? I know your supposed to UV unwrap before you animate, but I noticed with blender when you go into edit mode it resets the model to its original pose, I thought It wouldn't matter if I animated it first and wanted to make sure I didn't have to edit any geometry before I UV unwrapped it again.

Anyone know whats causing this? I am just marking my seams, hitting Ctrl A and then unwrap, but the highlighted square in the image shows what happens if I do it.

Cheersenter image description here

All of your UV Vertices are Pinned.

pinned

To Unpin select them all - A then Alt+P.

Next hover your 3D model and U > Unwrap and lastly (optional) back to UV Image Editor and Ctrl+P to Pack Islands.

result
