How to deactivate the red lines I am following a tutorial to create a 3D model. Then I accidentally pressed a button and the edges turn red. It is hard to see and how can I deactivate it? Thank You.
With default theme, these red lines are seams (cuts for UV unwrapping).

To get rid of it, in edit mode: select all and clear seam.

U then &quot;clear seams&quot;
